node:crypto, webcrypto: a fourth batch of Node compatibility fixes - #47671
Independent fixes, following #47559, #47567 and #47591. Every behaviour below was compared with Node v26.12.1.
RSA PKCS#1 v1.5 signatures
sign() and verify() work with sha512-224, sha512-256, sha3-224, sha3-256, sha3-384, sha3-512 and ripemd160, in node:crypto and in WebCrypto's RSASSA-PKCS1-v1_5 with SHA3-256, SHA3-384 and SHA3-512. sign() threw, and verify() returned false for a valid signature, while generateKey(), importKey() and supports() accepted those hashes. BoringSSL's table of DigestInfo prefixes had no row for them. RSA: PKCS#1 v1.5 signatures with seven more digests boringssl#16 adds the seven rows, and this moves the pin to the commit that merged it. Return CRYPTO_memcmp's accumulator through a value barrier boringssl#13, merged before it, comes along: CRYPTO_memcmp() returns its result through a value barrier so that Clang 23 vectorizes the loop. Nothing changes in Bun's own code. The signatures are byte for byte Node's.
.claude/commands/upgrade-boringssl.md lists the BoringSSL patch among those to keep.
process.send() of a CryptoKey
With serialization: "advanced", a CryptoKey that is not extractable is a DataCloneError, as it already is when serializing for storage. An extractable one is sent as before. structuredClone() and postMessage() are unchanged.
Buffers and encodings
An ArrayBuffer or a SharedArrayBuffer is taken wherever Node's getArrayBufferOrView() takes one: the keys, primes and generators of DiffieHellman and ECDH, ECDH.convertKey(), add and rem of generatePrime(), a cipher's iv, setAAD() and setAuthTag(), the signature of verify(), and a passphrase. They were ERR_INVALID_ARG_TYPE. cipher.update() still refuses one, like Node.
crypto.verify() takes a string for the signature.
In those places a hex string of odd length loses its last digit, like Buffer.from(). It was ERR_INVALID_ARG_VALUE, which is what the update() methods still throw, like Node's.
DiffieHellman, ECDH and sign.sign() refuse an output encoding they do not know with ERR_UNKNOWN_ENCODING. They returned a Buffer.
createSecretKey(), createPublicKey() and createPrivateKey() refuse an encoding they do not know. It meant UTF-8. "buffer" means UTF-8 in createSecretKey() too, where it threw.
cipher.update() reads a string as UTF-8 when it does not know the encoding, like the other update() methods. It was ERR_UNKNOWN_ENCODING.
Where Buffer.from() reads the string, an encoding that is not a string means UTF-8, and of the spellings of "buffer" only that one does. 5 was ERR_UNKNOWN_ENCODING, and "BUFFER" meant UTF-8.
checkPrime() does not take a string.
ECDH.convertKey() answers an empty key with an empty string.
Deleted: the arrayBufferViewOnly parameter of getArrayBufferOrView2(), three copies of the code that reads an input encoding, and four copies of the code that reads add and rem.
Diffie-Hellman and primes
dh.computeSecret() reports ERR_CRYPTO_INVALID_KEYLEN, "Supplied key is too small" or "too large". It was ERR_CRYPTO_INVALID_KEYTYPE, "Supplied key is invalid". DHPointer::checkPublicKey() is upstream ncrypto's again, which no longer leaves BoringSSL out.
crypto.diffieHellman() takes its keys in every form that sign() does (PEM, DER, JWK, with a passphrase), which Node added. It only took KeyObjects. Two kinds of key that do not go together are ERR_CRYPTO_INCOMPATIBLE_KEY. An error about a key names its option, as in options.publicKey.key.
checkPrime() runs at least BN_prime_checks_for_validation checks, which is what BoringSSL asks for on a number it did not draw itself.
Keys
node:crypto reads an EC JWK the way Node's ImportJWKEcKey does. The JWK decides whether it is a private key, so createPublicKey() and the functions that take a key check d too, where they ignored it. Every failure is ERR_CRYPTO_INVALID_JWK, or ERR_CRYPTO_INVALID_CURVE for a curve that is not known.
For EC, OKP and AKP keys the whole JWK is read before createPrivateKey() says that it holds no private key.
An ECPrivateKey in DER (type: "sec1") may leave out its public key. BoringSSL's d2i_PrivateKey_bio() tells the kind of key by the number of elements and took it for an RSA key.
A private key is exported with the ciphers aes128, aes192, aes256 and des3. createCipheriv() knew the first three.
A private key has no "raw-public" format.
A PEM may start with a UTF-8 byte order mark, which OpenSSL's reader skips. That goes for new X509Certificate() too.
Sign and Verify
One that was already used is ERR_CRYPTO_INVALID_STATE, "Not initialised".
Neither takes an Ed25519 or ML-DSA key: ERR_CRYPTO_UNSUPPORTED_OPERATION.
Both report what is wrong in Node's order: the options, the kind of key, then whether the object was used.
sign() reports BoringSSL's error when it cannot sign. It was a TypeError without a code.
verify() returns false for a padding or a salt length that the key does not take. It threw.
verify() throws "Malformed signature" for an ieee-p1363 signature of the wrong length. It returned false, which is what crypto.verify() returns in Node too.
dsaEncoding is read from any object. On a Proxy it was ignored.
Digests
Every function that takes the name of a digest looks it up in one table, without regard to case, like OpenSSL. The table holds the names in Node's getHashes() for the digests that BoringSSL has.
createHash(), createHmac(), hkdf() and sign() refused "Sha256".
Each function knew a different set of aliases: hash() and pbkdf2() did not know "RSA-SHA256", and createHmac() did not know "rmd160".
None knew "ripemd", "ssl3-md5", "sha2-256", "RSA-SHA3-256" or "sha512-256WithRSAEncryption".
The names that only Bun has ("sha128", "sha-512_256", "blake2b256" and so on) still work everywhere they did.
Deleted: about 80 lines of nested comparisons in ncrypto.cpp, and pbkdf2()'s use of the table of Bun.CryptoHasher.
createHmac() and hkdf() take blake2b512, which BoringSSL has.
getHashes() lists that table, so it cannot differ from what is accepted: 62 names, sorted, where it had 14. SHAKE and BLAKE2s are not in it, as before. Only createHash() and hash() have them, and Node's own tests take a listed name to work in pbkdf2() and hkdf() too.
getCurves() is sorted.
crypto.hash() is a port of Node's, over a native one-shot digest.
It takes { outputEncoding, outputLength }.
It knows the names that createHash() knows.
It still takes an ArrayBuffer, a Blob and a String object, and still writes the digest into a TypedArray or a DataView given as the third argument. Node's does neither.
Its errors are Node's.
hash() and createHash() throw for functionName and customization, the options of cSHAKE, which BoringSSL does not have. They were ignored, so the result was plain SHAKE.
SHAKE without an outputLength emits DEP0198.
hash and mgf1Hash of rsa-pss key generation are "no longer supported", as in Node 26. They emitted DEP0154.
WebCrypto
importKey("spki") and importKey("pkcs8") of an Ed25519 or X25519 key use BoringSSL's parser, like the other kinds of key. The code had a FIXME asking for that.
It stepped over tags and lengths without reading them. It took a key with another outer tag, any outer length, any version, or a wrong inner length.
A PrivateKeyInfo with attributes, which is valid, is now imported.
A length that is not minimal, and version 1 without a public key, are now refused, as they are for RSA, EC and ML-DSA keys.
The file is 112 lines shorter.
An entry of a JWK's key_ops that is not known is skipped. The specification has sequence<DOMString> there, and Node's validateKeyOps() skips it too. It was a TypeError. A repeated entry is still a DataError, known or not.
RSA-PSS: verify() with a saltLength of 2^31 or more is false, like any other salt length that the signature does not have. It was an OperationError.
An EC private key that was imported with a compressed public point is exported as pkcs8 with the whole point.
The shape of a few results
getCipherInfo() returns an object without a prototype that always has Node's six properties, in Node's order. One that does not apply is undefined.
The JWK of an Ed25519 or X25519 key has its members in Node's order: kty, crv, x, d.
crypto.getRandomValues.name is "getRandomValues".
new X509Certificate() throws Node's ERR_INVALID_ARG_TYPE for what is neither a string nor bytes. Without an argument it was ERR_MISSING_ARGS. A detached view is empty, as everywhere else.
How did you verify your code works?
Test file
What it covers
test/js/node/crypto/node-crypto.test.js
An ArrayBuffer and a SharedArrayBuffer in each place that takes one. Output encodings and odd hex strings of DiffieHellman and ECDH. computeSecret() with six other keys around the limits. checkPrime() with a string. Sign and Verify: used twice, with an Ed25519 key, with options the key does not take, with malformed signatures, with a Proxy. diffieHellman() with keys as PEM, DER and JWK, sync and async, and its errors
test/js/node/crypto/crypto.test.ts
30 aliases of seven digests, in mixed case, through the seven functions that take a name. HMAC and HKDF with blake2b512 against Node's results. The names that only Bun has. Seven names that must stay unknown. Every name in getHashes() through createHash(), hash(), pbkdf2Sync() and hkdfSync(). getCipherInfo() of a block, an ECB and a stream cipher
test/js/web/crypto/web-crypto.test.ts
For Ed25519 and X25519: a round trip of both formats, attributes, and 24 malformed encodings. key_ops with unknown, repeated and malformed entries, in importKey() and unwrapKey(). A compressed point in pkcs8 for ECDSA and ECDH
test/js/node/crypto/x509.test.ts
new X509Certificate() with nothing, null, a number, an object, a detached view and a byte order mark
test/js/node/crypto/crypto-oneshot.test.ts
The inputs, options, errors and output lengths of hash(), replaced built-ins, the options of cSHAKE, and when DEP0198 is emitted
test/js/node/crypto/crypto.key-objects.test.ts
Ten wrong EC JWKs with createPrivateKey() and createPublicKey(), an ECPrivateKey without its public key, the encoding of a key, the four ciphers, a byte order mark
test/js/node/crypto/crypto-rsa.test.js
The seven digests with sign(), createSign(), verify() and createVerify(), each signature against a fingerprint of the one Node makes. The three SHA-3 hashes with subtle.sign() and subtle.verify(). hash and mgf1Hash for rsa-pss
The new tests fail without the change: on 1.4.4, or on a debug build of main for node-crypto.test.js, which needs a debug build to load.
The 161 tests under test/js/node/test/parallel whose names start with test-crypto, test-webcrypto, test-x509, test-wasi or test-tls-check-server-identity pass.
Eight tests expected what an older Node did, and now expect what v26.12.1 does:
node-crypto.test.js: a string signature for crypto.verify(), and "raw-public" from a private key (two tests).
ecdh.test.ts: ECDH.convertKey() of a string that is not hex.
sign-jwk-ieee-p1363.test.ts: a DER signature given as ieee-p1363.
crypto-oneshot.test.ts: {} as the third argument of hash().
web-crypto.test.ts: verify() with a saltLength that does not fit an int. It still checks that such a value does not select a salt length.
node-crypto.test.js: 25 of Node's names for digests were listed as unsupported. They are now compared with Node's digests, which the test already had.
Deleted: the test in crypto.key-objects.test.ts for an error thrown while DEP0154 is emitted.
Two tests in web-crypto.test.ts used key_ops: ["bogus"] to make the conversion of a JWK throw. They use key_ops: 5 now, which still does.
test-crypto-dh.js is v26.12.1's. test-crypto-sign-verify.js takes four of its assertions from there, three of which replace expectations that were written for BoringSSL.
crypto.hash() goes through Bun.CryptoHasher.hash() only to write into a view. In one release build of this branch, crypto.hash("sha256", "hello world") takes 367 ns and Bun.CryptoHasher.hash() with the same arguments 476 ns. createHash() with two names in turn, which misses the one-entry cache in front of the table, takes 1549 ns for the pair, and 1773 ns on 1.4.4.
A script runs 326 spellings of digest names through eight functions. Where Bun and Node both accept a name, the results are the same, and no name that worked before is refused now.
BoringSSL's BN_generate_prime_ex() did not return for most values of `add`
(3, 10, 12, ...), nor for a safe prime with an odd `add`, and gave 7523 for
every small size. oven-sh/boringssl#16 fixes the search there, after
OpenSSL's, so this moves the pin to that commit.
That commit also refuses safe primes of 4 and 5 bits, so ncrypto.cpp no
longer has to.

Serializing for storage already refuses one. Sending to another process with
"advanced" serialization now does too. Extractable keys are sent as before,
and structuredClone() and postMessage() are unchanged.

Moves the pin to the second commit of oven-sh/boringssl#16. With the first
one alone, crypto.createDiffieHellman(2) had started to succeed.

Walkthrough
The pull request updates crypto bindings and runtime digest handling. It changes key parsing, prime generation, Diffie-Hellman, signing, verification, cipher input validation, and one-shot hashing. It also updates crypto tests, the BoringSSL revision, and non-extractable CryptoKey transfer serialization.
Input conversion updates encoding validation and ArrayBuffer handling. Key parsing and export change PEM BOM handling, SEC1 DER parsing, EC JWK validation, and raw-public validation. X509 certificate construction accepts ArrayBuffer inputs. Tests cover key and certificate input cases.
Diffie-Hellman and prime operations scripts/build/deps/boringssl.ts, .claude/commands/upgrade-boringssl.md, src/jsc/bindings/ncrypto.cpp, src/jsc/bindings/ncrypto.h, src/jsc/bindings/node/crypto/CryptoDhJob.cpp, src/jsc/bindings/node/crypto/CryptoPrimes.cpp, src/jsc/bindings/node/crypto/DiffieHellmanFunctions.h, test/js/node/crypto/node-crypto.test.js, test/js/node/test/parallel/test-crypto-dh.js
The BoringSSL revision and preserved-patch list change. Prime checks, prime input parsing, and safe-prime generation behavior change. Diffie-Hellman accepts converted key options and reports distinct public-key validation results. Tests cover these operations and their inputs.
Signing and verification src/jsc/bindings/node/crypto/CryptoSignJob.cpp, src/jsc/bindings/node/crypto/JSSign.cpp, src/jsc/bindings/node/crypto/JSVerify.cpp, src/jsc/bindings/node/crypto/CryptoUtil.cpp, test/js/node/crypto/sign-jwk-ieee-p1363.test.ts, test/js/node/crypto/node-crypto.test.js, test/js/node/test/parallel/test-crypto-sign-verify.js
Signing and verification change context-state errors, accepted key variants, signature conversion, and verification results. Tests cover malformed signatures, accepted input types, and streaming Ed25519/Ed448 errors.
Digest aliases and lookup change across crypto APIs. The binding exposes getHashes and oneShotDigest; crypto.hash validates its options and emits SHAKE deprecation warnings. PBKDF2 stores and uses a resolved digest. Tests cover digest aliases and one-shot hash behavior.
The crypto compatibility updates still contain a reported typecheck failure and several bounded validation, error-reporting, and test-coverage issues. Fix the Hash options typing before merging and address or explicitly accept the remaining concerns.

Explanation
The title "node:crypto, webcrypto: a fourth batch of Node compatibility fixes" is partially related to the changeset. The PR does contain many node:crypto and WebCrypto compatibility fixes compared against Node v26.12.1, which matches the PR objectives. However, the title is broad and does not name a specific primary change such as the BoringSSL pin update, the RSA PKCS#1 v1.5 DigestInfo prefixes, or the one-shot crypto.hash() rewrite. It describes the batch in general terms rather than the most important change. It is not vague or generic in the sense of "misc updates", so it does not warrant INCONCLUSIVE.

Post the readiness message after the crypto module loads.
The worker posts searching before it loads node:crypto. The parent calls worker.terminate() on that message. If termination lands before generatePrimeSync starts, the search never runs, and the test passes even when the search cannot be interrupted.
Loading the module first moves the readiness message next to the search call and shrinks that window.

In the worker script, load node:crypto before posting the "searching" readiness
message, then invoke generatePrimeSync as before. Update the script passed to

With sha512-224, sha512-256, sha3-224, sha3-256, sha3-384, sha3-512 and
ripemd160, sign() threw and verify() returned false for a valid signature,
in node:crypto and in WebCrypto's RSASSA-PKCS1-v1_5. BoringSSL's table of
DigestInfo prefixes had no row for them. oven-sh/boringssl#16 adds the rows,
so this moves the pin to its head.

Add a negative WebCrypto verify case for the SHA-3 RSASSA tests.
The new with %s in WebCrypto cases in test/js/node/crypto/crypto-rsa.test.js assert only that crypto.subtle.verify returns true for the matching signature and data. A verify that always returns true passes them. Add an assertion that crypto.subtle.verify returns false for a different data value, as the Node-level block already does for crypto.verify.

Review comment at @test/js/node/crypto/crypto-rsa.test.js at line 394:
Add a negative verification assertion to the SHA-3 RSASSA WebCrypto cases
alongside the existing positive assertion in the “with %s in WebCrypto” test,
verifying that the signature returns false for different data while preserving
the matching-data check.
The new RSA test checks only that createVerify(digest).update(data).verify(...) returns true for the valid signature. The negative check at line 385 calls one-shot crypto.verify, which runs through a different native entry point than the streaming method. A regression in the streaming path that accepts altered data would not fail these tests.

Review comment at @test/js/node/crypto/crypto-rsa.test.js at line 384:
Add a negative assertion alongside the streaming verification check using

expect `false`. Keep the existing one-shot `crypto.verify` assertion unchanged.

- An ArrayBuffer or a SharedArrayBuffer is taken wherever Node's
getArrayBufferOrView() takes one: the keys, primes and generators of
DiffieHellman and ECDH, `add` and `rem` of generatePrime(), a cipher's iv,
AAD and auth tag, a signature to verify, and a passphrase. cipher.update()
still refuses one, like Node.
- crypto.verify() takes a string for the signature.
- In those places a hex string of odd length loses its last digit, like
Buffer.from(). The update() methods still refuse one.
- DiffieHellman and ECDH refuse an output encoding they do not know. They
returned a Buffer.
- ECDH.convertKey() answers an empty key with an empty string.
- dh.computeSecret() reports ERR_CRYPTO_INVALID_KEYLEN, "too small" or "too
large". ncrypto's checkPublicKey() is upstream's again, which no longer
leaves BoringSSL out. test-crypto-dh.js is v26.12.1's.
- checkPrime() does not take a string, and runs at least the number of
checks that BoringSSL asks for on a number it did not draw itself.

Beyond the inline findings, I also checked whether the new non-extractable gate in SerializedScriptValue.cpp should extend to the sibling node:crypto KeyObject clone path at line 1485 — it should not: KeyObject has no extractable flag and Node clones it over IPC, so that path is correctly left alone. The exact small-prime expectations (3, 11, 401) in node-crypto.test.js are the only candidates at those sizes, so they are deterministic regardless of the random search start.
Extended reasoning...
The change bumps the BoringSSL fork pin to pick up a BN_generate_prime_ex add/safe fix and PKCS#1 v1.5 digest prefixes, deletes the Bun-side 4/5-bit safe-prime guard in ncrypto.cpp, and extends the CryptoKey DataCloneError in SerializedScriptValue.cpp to cross-process transfer. It touches crypto code paths (prime generation, RSA signing, key serialization), so the inline findings plus a human look are warranted; the note above records the sibling paths examined and ruled out.
Findings marked 🟡 are optional suggestions and need no follow-up push.
Additional findings (outside the current diff — GitHub can't attach inline comments there):
🟣 src/jsc/bindings/ncrypto.cpp — Users who call crypto.createDiffieHellman(bits) in a Worker still cannot terminate it until the whole safe-prime search finishes, even though this PR advertises interruptible prime searches. DHPointer::New at src/jsc/bindings/ncrypto.cpp:1389 passes nullptr as the BN_GENCB, so the new fork search runs with no scriptAllowed poll. Fix: pass the same whileScriptAllowed-backed callback into DH_generate_parameters_ex (every caller of the changed search), as BignumPointer::generate does at ncrypto.cpp:399-417.
Why this was flagged
crypto.createDiffieHellman(2048, 2) from src/jsc/bindings/node/crypto/JSDiffieHellmanConstructor.cpp:116 enters DH_generate_parameters_ex at src/jsc/bindings/ncrypto.cpp:1389 with a nullptr callback; BoringSSL turns that into BN_generate_prime_ex(p, bits, 1, 24, 11, NULL), the same search the PR…
Verification: pre-existing — trigger: createDiffieHellman(bits, generator) running inside a Worker while the safe-prime search is in progress. src/jsc/bindings/ncrypto.cpp:1389 passes a null BN_GENCB, so the search never polls anything; BignumPointer::generate (ncrypto.cpp:398-417) installs a BN_GENCB. The base commit has the identical nullptr, so merging makes nothing worse.
- An EC JWK is read the way Node's ImportJWKEcKey reads it. The JWK decides
whether it is a private key, so createPublicKey() and the functions that
take a key check `d` too: it was ignored there. Every failure is
ERR_CRYPTO_INVALID_JWK, or ERR_CRYPTO_INVALID_CURVE for an unknown curve.
- For EC, OKP and AKP keys the whole JWK is read before createPrivateKey()
says that it holds no private key.
- An ECPrivateKey in DER may leave out its public key.
- An `encoding` that is not known is ERR_UNKNOWN_ENCODING in
createSecretKey(), createPublicKey() and createPrivateKey(), where it meant
UTF-8. "buffer" means UTF-8 in createSecretKey() too.
- A private key is exported with the ciphers aes128, aes192, aes256 and des3,
which createCipheriv() knew apart from the last.
- A private key has no "raw-public" format.
- A PEM may start with a byte order mark.

- A Sign or a Verify that was already used is ERR_CRYPTO_INVALID_STATE.
- Neither takes an Ed25519 or ML-DSA key: ERR_CRYPTO_UNSUPPORTED_OPERATION.
- sign() refuses an output encoding it does not know, and reports
BoringSSL's error when it cannot sign. It was a TypeError without a code.
- verify() returns false for a padding or a salt length that the key does not
take. It threw.
- verify() throws "Malformed signature" for an ieee-p1363 signature of the
wrong length. It returned false, as crypto.verify() does in Node too.
- `dsaEncoding` is read from any object. A Proxy was taken for "der".
- crypto.diffieHellman() takes its keys in every form that sign() does, not
only as KeyObjects, and reports two kinds of key that do not go together as
ERR_CRYPTO_INCOMPATIBLE_KEY.

OpenSSL answers -2 for one, which Node throws for. BoringSSL answers 0, so
looking for -2 alone had turned the error into `false` for an X25519 key.

Build #136595 has 41 failing files. All of them are AOT tests: 40 under test/aot/, and test/bundler/compile-aot-size.test.ts.
40 of the 41 fail in main's own build at this branch's base, #136408 (3f3a9ff). That commit is still the tip of main, so there is no fix to merge in yet.
The other one is test/aot/heap-limit.test.ts, which crashed on one lane (🐧 13 x64).
This PR does not touch the AOT compiler or its tests. No crypto, WebCrypto, TLS or child_process test failed in the jobs that finished. The next push cancelled six jobs.
I cannot re-run jobs from here. I will merge main once it has a fix.
The worker loaded node:crypto after it posted its message, so terminate()
usually arrived before the search began. On a build that cannot interrupt the
search the test still passed 7 times out of 8. Now it fails there every time.
Also check that a signature with one of the new digests does not verify other
data, with Verify and in WebCrypto.

The merge-base record meets the attribution bar, so it does not belong in this PR's review. The pinned BoringSSL source remains uninspected. Revisit this decision only if the pinned pem_lib.cc shows a change to the start-line check. No such evidence exists here.
The corrected text below is retained for the record. It is not for publication on this PR.
Strip the UTF-8 BOM before parsing in X509Pointer::Parse.
X509Pointer::Parse passes the raw buffer to BIO_new_mem_buf. A PEM certificate that starts with EF BB BF fails the -----BEGIN start-line check, so the PEM branch fails. The DER fallback then reads the same BIO from the BOM byte and also fails. The key paths already skip the BOM, so a BOM-prefixed PEM key parses while the same certificate does not.
Suggested fix
Move SkipByteOrderMark above X509Pointer::Parse, because the helper is defined later in the file:
The DER fallback reads the same BIO, so it parses the stripped bytes. This changes results only for input that starts with the BOM. A valid DER certificate starts with 0x30.

BIO_new_mem_buf, so both PEM parsing and the DER fallback read the BOM-stripped
input. Move SkipByteOrderMark above X509Pointer::Parse so it is available at the

The round-trip check at lines 745-746 also passes for an unencrypted PEM. An import with a passphrase does not fail for an unencrypted key. A regression that drops cipher would therefore pass this test. Add assertions on pem that require encryption: the PEM must match pkcs8EncExp, and a passphrase-less import must throw.

Still open from earlier reviews (1):
Unresolved: 1 minor or pre-existing.
Additional findings (outside the current diff — GitHub can't attach inline comments there):
🟣 src/jsc/bindings/node/crypto/CryptoUtil.cpp — nit, pre-existing: callers who pass a truthy non-string input encoding to DH, ECDH, cipher or Verify methods get ERR_UNKNOWN_ENCODING where Node reads the string as UTF-8. src/jsc/bindings/node/crypto/CryptoUtil.cpp:661-666 sends any truthy encodingValue through parseEnumerationAllowBuffer, which returns nullopt for a non-string, and then throws. The new getInputEncoding at CryptoUtil.cpp:604 already does what Node does (non-string means utf8) but this sibling overload was left out. Fix: make the JSValue-encoding overload of getArrayBufferOrView decide the string encoding the way getInputEncoding does, keeping the defaultBufferEncoding=true path used by createDiffieHellman's sizeOrKey.
Why this was flagged
dh.computeSecret("abc", 5) or verifier.verify(key, "sig", 5) reaches getArrayBufferOrView(JSValue encoding) at src/jsc/bindings/node/crypto/CryptoUtil.cpp:655 with a string value. Line 661 sees pureToBoolean() == True for the number 5 and calls WebCore::parseEnumerationAllowBuffer, which returns std::nullopt for anything that is not a string (src/jsc/bindings/JSBufferEncodingType.cpp:54). Since defaultBufferEncoding is false at every caller except JSDiffieHellmanConstructor.cpp:125, line 665 throws ERR_UNKNOWN_ENCODING. Node's getArrayBufferOrView calls Buffer.from(string, encoding), whose fromString treats typeof encoding !== 'string' as UTF-8 and never throws, so Node returns a result here. The base branch behaves the same way as the PR at this site; the PR adds getInputEncoding (CryptoUtil.cpp:602-619) with Node's rule for the other three string-decoding sites but does not apply it to this overload.
Verification: pre-existing. src/jsc/bindings/node/crypto/CryptoUtil.cpp:661 calls parseEnumerationAllowBuffer for the number 5, which at src/jsc/bindings/JSBufferEncodingType.cpp:54-56 returns std::nullopt for any non-string; then line 664 throws ERR::UNKNOWN_ENCODING. Node's Buffer.from(string, enc) treats a non-string enc as utf8, not a throw. Lines 661/664 are unchanged from the base.
- Every function that takes the name of a digest looks it up in one table of
the names in Node's getHashes(), without regard to case. createHash(),
createHmac(), hkdf() and sign() refused "Sha256". Each function knew a
different set of aliases, and none knew "ripemd", "ssl3-md5", "sha2-256",
"RSA-SHA3-256" or "sha512-256WithRSAEncryption". pbkdf2() had its own table.
- createHmac() and hkdf() take blake2b512, which BoringSSL has.
- getHashes() lists that table: 62 names, sorted, where it had 14. It leaves
out SHAKE and BLAKE2s, which only createHash() and hash() have, because
Node's tests take a listed name to work in pbkdf2() and hkdf() too.
- getCurves() is sorted.
- hash() is a port of Node's. It takes { outputEncoding, outputLength },
knows the names that createHash() knows, refuses an ArrayBuffer, and no
longer writes the digest into a TypedArray given as its third argument.
- hash() and createHash() throw for the options of cSHAKE, which BoringSSL
does not have, where they computed SHAKE.
- SHAKE without an outputLength is DEP0198.
- `hash` and `mgf1Hash` of rsa-pss key generation are "no longer supported",
as in Node 26. They were DEP0154.

Test passes when termination lands before the native search starts.
The new worker test posts "searching" and then calls generatePrimeSync(64, { add: 6n, rem: 3n }). The parent calls worker.terminate() when it receives that message. The parent runs on another thread, so termination can land after the postMessage and before the native call. In that schedule the worker stops at a JavaScript point, and the test still prints "terminated" with exit code 0. The test therefore passes on a build whose native prime search cannot be interrupted.
The test does not check that the search was running at termination. Add a check that confirms the native search started before termination, or assert on a different outcome that only an interrupted search produces. Either change would make the test detect the non-interruptible case reliably.

Review comment at @test/js/node/crypto/node-crypto.test.js around lines 1318 -
1319:
Update the worker termination test around generatePrimeSync so it only passes
when termination interrupts an active native prime search, not when the worker
stops before the call begins. Add synchronization that confirms the search has
started before the parent calls worker.terminate(), or assert an outcome that
can only result from interrupting the search.

- getCipherInfo() returns an object without a prototype that always has
Node's six properties, in Node's order. One that does not apply is
undefined.
- The JWK of an Ed25519 or X25519 key has its members in Node's order: kty,
crv, x, d.
- crypto.getRandomValues has its name.
- new X509Certificate() throws Node's ERR_INVALID_ARG_TYPE for what is neither
a string nor bytes. Without an argument it was ERR_MISSING_ARGS. A detached
view is empty, as everywhere else.

- importKey("spki") and importKey("pkcs8") of an Ed25519 or X25519 key use
BoringSSL's parser, like the other kinds of key. The code stepped over tags
and lengths without reading them, so it took a key with another outer tag,
any outer length, any version or a wrong inner length. A PrivateKeyInfo with
attributes, which is valid, is now imported.
- An entry of a JWK's `key_ops` that is not known is skipped, as the
specification and Node have it. It was a TypeError. A repeated one is still
a DataError.
- RSA-PSS: verify() with a saltLength of 2^31 or more is false, like any other
salt length that the signature does not have. It was an OperationError.
- An EC private key that was imported with a compressed public point is
exported as pkcs8 with the whole point.
Co-authored-by: dylanc <dylanc@anthropic.com>
- createPrivateKey({ format: "der", type: "sec1" }) takes a key that is not an
ECPrivateKey again, as it did and as Node does. Reading every such key as an
EC key had refused RSA and Ed25519 keys.
- verify.verify() reports what is wrong in Node's order: the options, then the
kind of key, then whether the object was used.
- An error about the `key` of an option of diffieHellman() names the option.
- new X509Certificate() skips a byte order mark too.
- cipher.update() reads a string as UTF-8 when it does not know the encoding,
like the other update() methods. It was ERR_UNKNOWN_ENCODING.
- An input encoding that is not a string is UTF-8, as in Buffer.from(). It was
ERR_UNKNOWN_ENCODING.

Beyond the inline findings, I also checked the four new it.each blocks in test/js/web/crypto/web-crypto.test.ts (lines 1829, 1845, 1864, 1869) whose expect(...).rejects.toThrow(...) is not awaited: a failing expectation still surfaces as an unhandled rejection that fails the file, so they are not vacuous, though an await would attribute a failure to the right case.
Extended reasoning...
The latest two commits add Ed25519/X25519 DER parsing tests and JWK key_ops tests to web-crypto.test.ts; the un-awaited rejects pattern there was examined and found to still fail the run on regression. The PR remains a large node:crypto and WebCrypto change, so the inline findings and the still-open AOT built-in table thread from the prior review stand as the reasons a human look is needed.
Findings marked 🟡 are optional suggestions and need no follow-up push.
If you have decided not to act on one of these findings, resolve its thread (a reply alone leaves it open) and the next review stops counting it. To review this commit again now, use Re-run on its "Claude Code Review" check.
Node checks outputLength, then functionName, then customization, before it looks the digest up (hash.js#L110-L147). It reads outputLength only when typeof options === "object".
The branch robobun/9bce678e/createhash-cshake-options does these checks in constructHash. It has 17 node:assert cases for the rows above, which also pass on Node v26.12.1. Use any part of it that helps.

…from review
- The table of built-ins lists the members of the C++ binding of node:crypto.
getHashes moved there and oneShotDigest is new, and neither was listed. The
test of that table failed.
- crypto.hash() keeps ArrayBuffer.isView and String.prototype.toLowerCase from
when the module was loaded, so replacing them later changes nothing.
- The native half checks its input first, before an output length of 0 returns.
- The options of createHash() have their types.
- The test of unknown digest names expects each function's own error.
Co-authored-by: dylanc <dylanc@anthropic.com>
- crypto.hash() takes an ArrayBuffer, a Blob and a String object again, as it
did before this branch. bun-cryptohasher.test.ts expects that of an output of
Bun.build().
- Repeated entries of a JWK's key_ops are found with a set. Each entry was
compared with all the entries before it.
- Every error of crypto.diffieHellman() about a JWK or a raw key names the
option, as in `options.publicKey.asymmetricKeyType`.
- Where Buffer.from() reads a string, "BUFFER" is not an encoding. Only
"buffer" means UTF-8.
- Deleted bytesUsedToEncodedLength(), which nothing calls now.

A TypedArray or a DataView as the third argument got the digest written into
it, because hash() was Bun.CryptoHasher.hash(). The port of Node's hash() took
it for an options object without options, returned a hex string and left the
view as it was, without an error. It goes to Bun.CryptoHasher.hash() again.

The patch no longer goes back to its caller every 1024 steps, and it treats
small candidates the way OpenSSL does. A search for a prime that does not exist
cannot be interrupted, as before this branch and as in Node, so the test for
that goes.

The BoringSSL branch no longer changes BN_generate_prime_ex(), so the pin
moves to its new head, which has only the rows for PKCS#1 v1.5 signatures.
BignumPointer::generate() gets its check for safe primes of 4 and 5 bits
back and is what it is on main. The test for `add` goes.

oven-sh/boringssl#16 was squashed, so the pin moves from its branch to the

…crypto fixes (#47820)
### What does this PR do?
Independent fixes, following #47559, #47567, #47591 and #47671. The
`node:crypto` behaviour below was compared with Node v26.12.1.
**`X509Certificate`**
- `checkHost()`, `checkEmail()`, `checkIP()`, `checkIssued()`,
`checkPrivateKey()` and `verify()` validate their arguments as Node
does, with its codes and messages. A name of `undefined` was read as
`"undefined"`, an array or a function was taken for options, and
`checkIP()` did not look at its options. `checkIP.length` is 2.
- The options are validated in the order of
[`getFlags()`](https://github.com/nodejs/node/blob/v26.12.1/lib/internal/crypto/x509.js#L59-L86):
every type first, then the value of `subject`. Like its `{ ...options
}`, only own enumerable properties count. Inherited and non-enumerable
ones were read too.
- `checkHost("")` is `undefined`, not an error.
- `validFromDate` and `validToDate` come from the time in the
certificate, through upstream ncrypto's `getValidFromTime()` and
`getValidToTime()`. They were parsed back from the printed date, which
put the years 0 to 99 in the 1900s and 2000s.
- `new X509Certificate()` of something that is not a certificate throws
the library's error, with `code`, `library` and `reason`. The code was
`ERR_CRYPTO_INVALID_STATE`.
- The values of `infoAccess` in the legacy certificate object are the
values themselves, as in Node. One that had to be escaped was left as a
JSON string. That object is what `toLegacyObject()`,
`getPeerCertificate()`, `getCertificate()` and `checkServerIdentity()`
give.
- Deleted: `throwBoringSSLError()`, which has no caller left, and the
message parameter of `handleMatchResult()`.
**`Bun.password`**
- `hash()` and `verify()` take what `hashSync()` and `verifySync()`
take, which is what their types say: a string or bytes.
- **This changes what is accepted.** They called `toString()` on any
other value but `undefined`. `await Bun.password.hash(1234)` gave a
hash, `await Bun.password.verify(null, hash)` gave `false`, and
`Bun.password.verify(password, null)` gave a promise that rejects. All
three now throw a `TypeError` with `ERR_INVALID_ARG_TYPE` from the call
itself, before there is a promise, as they already did for `undefined`.
Pass `String(1234)`.
**`Bun.CryptoHasher`**
- `digest(typedArray)` needs room for the digest, which is `byteLength`.
It asked for 64 bytes with every algorithm, so the example in the docs,
`digest(new Uint8Array(32))` with `sha256`, threw. What it writes is
unchanged.
- A hasher with a key that was already digested says so before it looks
at the argument of `digest()`.
### How did you verify your code works?
| File | What it covers |
|---|---|
| `test/js/node/crypto/x509.test.ts` | The name and the options of
`checkHost()`, `checkEmail()` and `checkIP()`, options that are
inherited or not enumerable, names that cannot be one, the arguments of
`checkIssued()`, `checkPrivateKey()` and `verify()`. Validity in the
years 0 to 99. Text, nothing, other DER and bad base64 given to the
constructor. The legacy `infoAccess` of Node's `x509-escaping` fixtures,
from `toLegacyObject()` and, over a TLS connection, from
`getPeerCertificate()`, `getCertificate()` and `checkServerIdentity()`.
|
| `test/js/bun/util/password.test.ts` | Eleven kinds of value that are
neither a string nor bytes, as the password of `hash()` and as the
password and the hash of `verify()`, in the async and the sync forms. An
`ArrayBuffer`, a `SharedArrayBuffer`, a `DataView` and a `Uint16Array`
as the password and as the hash. |
| `test/js/bun/util/bun-cryptohasher.test.ts` | For every algorithm, and
for every one that takes a key: an array of exactly `byteLength`, of one
more and of 100 more bytes gets the digest and nothing else, and one
byte less throws. `shake128` and `shake256` fill the array, and the
result is that of `createHash(algorithm, { outputLength })`. |
Of the 66 new tests, the 50 that cover a change fail on Bun 1.4.4. The
other 16 are rows for what stays the same: years from 100, the sync
forms, the kinds of bytes, 64-byte digests, and `checkIP()` with
inherited options, which it did not read. All pass on a debug build with
ASAN, also with `BUN_JSC_validateExceptionChecks=1`.
Changed tests: the five "rejects a body with ..." rows of `x509.test.ts`
expected `ERR_CRYPTO_INVALID_STATE` and expect the library's code. The
two tests named "coercion throwing doesn't crash" in `password.test.ts`
are rows of the new ones, since nothing is coerced.
Two scripts ran the same calls on Node v26.12.1, on Bun 1.4.4 and on
this branch. Of 142 calls with odd arguments, dates and certificates, 70
that differed from Node now give its result. Of 756 `checkHost()`,
`checkEmail()` and `checkIP()` calls, 138 do. No call that gave Node's
result gives another one now.
The 161 tests under `test/js/node/test/parallel` whose names start with
`test-crypto`, `test-webcrypto` or `test-tls-check-server-identity`
pass, and so do `test-tls-peer-certificate.js`,
`test-tls-peer-certificate-encoding.js`,
`test-tls-peer-certificate-multi-keys.js`,
`test-tls-getcertificate-x509.js`,
`test-tls-translate-peer-certificate.js` and
`test-tls-cert-ext-encoding.js`.

…ers before a key exists
ecdh.getPublicKey() and ecdh.getPrivateKey() reported ERR_CRYPTO_INVALID_STATE
when the object has no key. Node reports ERR_CRYPTO_OPERATION_FAILED from
ECDH::GetPublicKey and ECDH::GetPrivateKey in src/crypto/crypto_ec.cc. The
message already matched.
The change and its test come from #43508. The rest of that PR landed in #47671.

### What does this PR do?
Independent fixes. The behaviour below was compared with Node v26.12.1.
**`node:net`**
- A socket emits `'timeout'` when a write is waiting and does not move:
while the socket is connecting, while the TLS handshake is not finished,
or while the peer does not read. With a write waiting the event was
dropped and the timer was not started again, so `http.get(url, { timeout
})`, `new Agent({ timeout })` and `socket.setTimeout()` said nothing in
those cases. As in
[Node](https://github.com/nodejs/node/blob/v26.12.1/lib/net.js#L872-L887),
the timeout is put off only while what the handle has left to send keeps
changing, and a write that completes starts the timer again.
**`node:http`, `node:https`**
- `Agent` does not give a request a pooled socket that has something to
read, like [Node's
`hasPendingRead()`](https://github.com/nodejs/node/blob/v26.12.1/lib/_http_agent.js#L141-L151).
It asks `us_socket_queued_input()`, which the pool of `fetch()` already
asks.
- The change is also in the second text of the module, under
`src/js/ahead-of-time`, and the new binding is listed under the
`Sockets` feature of `--trim`, beside `getBufferedAmount`.
**`node:http2`**
- `http2.connect()` takes `maxOriginSetSize`, 128 by default. A session
that is sent more origins is destroyed with
`ERR_HTTP2_TOO_MANY_ORIGINS`.
**`node:stream`**
- `readable.setEncoding()` after the end of the stream keeps what the
decoder holds back. With `base64` and `base64url` the last one or two
bytes were lost, for example from a `Cipheriv` that had ended.
**`node:quic`**
- `session.peerCertificate` is read with `SSL_get_peer_certificate()`,
like the copy that is kept at the handshake. Deleted, with no caller
left: `leaf_certificate_der()`, `server_cert_chain()` with its `extern`,
and `sk_X509_pop_free()`.
**`node:worker_threads`**
- `receiveMessageOnPort()` throws when the message cannot be
deserialized.
- When a value thrown in a worker fails to deserialize in the parent
without an exception, `'error'` gets an `Error` with its description, as
for a value that cannot be serialized.
- `SerializedScriptValue::deserialize()` ends like WebKit's, with `null`
in place of an empty value.
**`node:crypto`**
- `createVerify().verify()` throws for an EC key with a digest that
BoringSSL has no ECDSA for (`md5`, `md5-sha1`, `ripemd160`,
`sha512-224`, `sha512-256`, `sha3-*`, `blake2b512`), like
`createSign().sign()`, `sign()` and `verify()`. Since #47671, which is
in no release, it returned `false`. With an RSA key, options that the
key does not take are still `false`, as in Node.
- In `publicEncrypt()`, `privateDecrypt()`, `privateEncrypt()` and
`publicDecrypt()`, a falsy `padding` (`null`, `0`, `false`, `""`, `NaN`,
`0n`) is the default padding, as in Node's `key.padding ||
defaultPadding`. It threw.
- The `ArrayBuffer` of what `createSign().sign()` returns is as long as
the signature. With an EC key it was a few bytes longer.
- A raw key is imported only with `asymmetricKeyType` spelled as Node
spells it. `"Ed25519"` and `"ML-DSA-44"` were taken. The error has
Node's message. Deleted: the `ignoreCase` parameter of
`pqcKeyTypeToNid()`.
- `format` of a key to import, and `type` of a `raw-public` export, are
compared with `===`, without conversion. `["jwk"]` and an object with
`toString()` were taken, and a symbol threw an error without a code.
- `Cipheriv.call(this, ...)`, `Decipheriv.call(this, ...)`,
`Hmac.call(this, ...)` and `Certificate.call(this)` initialize `this`
when it is an instance, so a function that inherits with
`util.inherits()` works. They test `this instanceof`, as Node does, and
no longer `new.target`.
**`Bun.password`**
- `verifySync()` copies a hash that is in a `SharedArrayBuffer`. Its
fields are parsed more than once, which is what `shared: "copied"` is
for.
**Types**
- The docs of `CryptoHasher#digest(hashInto)` say that `shake128` and
`shake256` fill all of the array.
### How did you verify your code works?
| File | What it covers |
|---|---|
| `test/js/node/net/node-net.test.ts` | `'timeout'` with a write
waiting: on a socket whose `lookup` never answers, on a TLS socket whose
peer never answers the handshake, and on a socket whose peer never
reads. |
| `test/js/node/http/client-timeout-error.test.ts` | `'timeout'` of a
request whose connection is never made. |
| `test/js/node/stream/node-stream.test.js` | `setEncoding()` after the
end with `base64`, `base64url` and `hex`. |
| `test/js/node/crypto/node-crypto.test.js` | An EC key with five of the
digests, in `createSign()` and `createVerify()`. The `ArrayBuffer` of a
P-521 signature. Eight values of `asymmetricKeyType` with the three raw
formats. An array, an object with `toString()`, a `String` object and a
symbol as `format` and as `type`. The four constructors called on an
instance and on another object. |
| `test/js/node/crypto/crypto-rsa.test.js` | Seven falsy values of
`padding` in the four functions. |
| `test/js/bun/util/password.test.ts` | `verifySync()` of a hash that a
`Worker` keeps writing. A password and a hash that are a part of a
larger buffer. |
From Node v26.12.1, unchanged: `test-http2-origin-set-max-size.mjs` is
new, and `test-stream-readable-setEncoding-existing-buffers.js` is
brought up to date. Both fail on Bun 1.4.4. `test-https-timeout.js`,
which did not end on a debug build, passes there.
Of the 38 new tests, 32 fail on Bun 1.4.4. Four more, the digests that
1.4.4 threw for, fail on `main`. The other two are rows for what stays
the same: `hex`, and a part of a larger buffer. All pass on a debug
build.
Changed tests:
- Four recorded outputs gain an own key of a socket,
`Symbol(lastWriteQueueSize)`, before the timeout slot, where Node has
it: `visible-surface.test.ts.snap`,
`node-http-own-keys-through-an-exchange.expected.txt`,
`node-http-own-values-through-an-exchange.expected.txt` and the output
of
`test/aot/parallel/node-http/objects-closed-proxies-without-traps.ts`.
- "is the same in the certificates of a TLS connection" in
`x509.test.ts` closes its sockets in `finally`.
- The `"banana"` line of "raw key formats reject unsupported
combinations" is a row of the new `asymmetricKeyType` test.
Scripts ran the same calls on Node v26.12.1, with these changes and
without them:
- Six ways to put a timeout on a request to a host that never completes
the TCP handshake, a handshake that is slower than the timeout, and a
peer that stops reading, over TCP and TLS. The seven rows that differed
from Node now give Node's result.
- When `'timeout'` comes, in 35 rows: a write that stalls, that moves
slowly or that completes just before the timer, and a handshake that
stalls or is slow, over TCP, TLS, an upgraded socket and a `Duplex`, on
the client and on the server. 30 rows changed, each to Node's times.
- 229 rows of `createSign()`, `createVerify()`, `sign()` and `verify()`:
50 digest names with three EC keys and an RSA key, and 29 combinations
of `padding` and `saltLength`. The 54 rows of the first `node:crypto`
item changed, and no other.
- `setEncoding()` after the end with six encodings and seven lengths.
The 12 rows that differed from Node now give Node's result.
The 1,959 tests under `test/js/node/test/parallel` and
`test/js/node/test/sequential` whose names start with `test-net`,
`test-http`, `test-tls`, `test-stream`, `test-crypto`, `test-webcrypto`,
`test-x509`, `test-worker`, `test-quic`, `test-timers`, `test-pipe`,
`test-socket`, `test-messag`, `test-broadcastchannel`,
`test-structuredClone`, `test-readable` or `test-writable` ran on a
release build with these changes and on one without. The two tests above
pass only with them, and every other test gives the same result.

What does this PR do?
Independent fixes, following #47559, #47567 and #47591. Every behaviour below was compared with Node v26.12.1.
RSA PKCS#1 v1.5 signatures
sign()andverify()work withsha512-224,sha512-256,sha3-224,sha3-256,sha3-384,sha3-512andripemd160, innode:cryptoand in WebCrypto'sRSASSA-PKCS1-v1_5withSHA3-256,SHA3-384andSHA3-512.sign()threw, andverify()returnedfalsefor a valid signature, whilegenerateKey(),importKey()andsupports()accepted those hashes. BoringSSL's table ofDigestInfoprefixes had no row for them. RSA: PKCS#1 v1.5 signatures with seven more digests boringssl#16 adds the seven rows, and this moves the pin to the commit that merged it. Return CRYPTO_memcmp's accumulator through a value barrier boringssl#13, merged before it, comes along:CRYPTO_memcmp()returns its result through a value barrier so that Clang 23 vectorizes the loop. Nothing changes in Bun's own code. The signatures are byte for byte Node's..claude/commands/upgrade-boringssl.mdlists the BoringSSL patch among those to keep.process.send()of aCryptoKeyserialization: "advanced", aCryptoKeythat is not extractable is aDataCloneError, as it already is when serializing for storage. An extractable one is sent as before.structuredClone()andpostMessage()are unchanged.Buffers and encodings
ArrayBufferor aSharedArrayBufferis taken wherever Node'sgetArrayBufferOrView()takes one: the keys, primes and generators ofDiffieHellmanandECDH,ECDH.convertKey(),addandremofgeneratePrime(), a cipher'siv,setAAD()andsetAuthTag(), the signature ofverify(), and apassphrase. They wereERR_INVALID_ARG_TYPE.cipher.update()still refuses one, like Node.crypto.verify()takes a string for the signature.Buffer.from(). It wasERR_INVALID_ARG_VALUE, which is what theupdate()methods still throw, like Node's.DiffieHellman,ECDHandsign.sign()refuse an output encoding they do not know withERR_UNKNOWN_ENCODING. They returned aBuffer.createSecretKey(),createPublicKey()andcreatePrivateKey()refuse anencodingthey do not know. It meant UTF-8."buffer"means UTF-8 increateSecretKey()too, where it threw.cipher.update()reads a string as UTF-8 when it does not know the encoding, like the otherupdate()methods. It wasERR_UNKNOWN_ENCODING.Buffer.from()reads the string, an encoding that is not a string means UTF-8, and of the spellings of"buffer"only that one does.5wasERR_UNKNOWN_ENCODING, and"BUFFER"meant UTF-8.checkPrime()does not take a string.ECDH.convertKey()answers an empty key with an empty string.arrayBufferViewOnlyparameter ofgetArrayBufferOrView2(), three copies of the code that reads an input encoding, and four copies of the code that readsaddandrem.Diffie-Hellman and primes
dh.computeSecret()reportsERR_CRYPTO_INVALID_KEYLEN, "Supplied key is too small" or "too large". It wasERR_CRYPTO_INVALID_KEYTYPE, "Supplied key is invalid".DHPointer::checkPublicKey()is upstream ncrypto's again, which no longer leaves BoringSSL out.crypto.diffieHellman()takes its keys in every form thatsign()does (PEM, DER, JWK, with a passphrase), which Node added. It only tookKeyObjects. Two kinds of key that do not go together areERR_CRYPTO_INCOMPATIBLE_KEY. An error about a key names its option, as inoptions.publicKey.key.checkPrime()runs at leastBN_prime_checks_for_validationchecks, which is what BoringSSL asks for on a number it did not draw itself.Keys
node:cryptoreads an EC JWK the way Node'sImportJWKEcKeydoes. The JWK decides whether it is a private key, socreatePublicKey()and the functions that take a key checkdtoo, where they ignored it. Every failure isERR_CRYPTO_INVALID_JWK, orERR_CRYPTO_INVALID_CURVEfor a curve that is not known.createPrivateKey()says that it holds no private key.ECPrivateKeyin DER (type: "sec1") may leave out its public key. BoringSSL'sd2i_PrivateKey_bio()tells the kind of key by the number of elements and took it for an RSA key.aes128,aes192,aes256anddes3.createCipheriv()knew the first three."raw-public"format.new X509Certificate()too.SignandVerifyERR_CRYPTO_INVALID_STATE, "Not initialised".ERR_CRYPTO_UNSUPPORTED_OPERATION.sign()reports BoringSSL's error when it cannot sign. It was aTypeErrorwithout acode.verify()returnsfalsefor a padding or a salt length that the key does not take. It threw.verify()throws "Malformed signature" for anieee-p1363signature of the wrong length. It returnedfalse, which is whatcrypto.verify()returns in Node too.dsaEncodingis read from any object. On aProxyit was ignored.Digests
getHashes()for the digests that BoringSSL has.createHash(),createHmac(),hkdf()andsign()refused"Sha256".hash()andpbkdf2()did not know"RSA-SHA256", andcreateHmac()did not know"rmd160"."ripemd","ssl3-md5","sha2-256","RSA-SHA3-256"or"sha512-256WithRSAEncryption"."sha128","sha-512_256","blake2b256"and so on) still work everywhere they did.ncrypto.cpp, andpbkdf2()'s use of the table ofBun.CryptoHasher.createHmac()andhkdf()takeblake2b512, which BoringSSL has.getHashes()lists that table, so it cannot differ from what is accepted: 62 names, sorted, where it had 14. SHAKE and BLAKE2s are not in it, as before. OnlycreateHash()andhash()have them, and Node's own tests take a listed name to work inpbkdf2()andhkdf()too.getCurves()is sorted.crypto.hash()is a port of Node's, over a native one-shot digest.{ outputEncoding, outputLength }.createHash()knows.ArrayBuffer, aBloband aStringobject, and still writes the digest into aTypedArrayor aDataViewgiven as the third argument. Node's does neither.hash()andcreateHash()throw forfunctionNameandcustomization, the options of cSHAKE, which BoringSSL does not have. They were ignored, so the result was plain SHAKE.outputLengthemits DEP0198.hashandmgf1Hashofrsa-psskey generation are "no longer supported", as in Node 26. They emitted DEP0154.WebCrypto
importKey("spki")andimportKey("pkcs8")of an Ed25519 or X25519 key use BoringSSL's parser, like the other kinds of key. The code had aFIXMEasking for that.PrivateKeyInfowith attributes, which is valid, is now imported.key_opsthat is not known is skipped. The specification hassequence<DOMString>there, and Node'svalidateKeyOps()skips it too. It was aTypeError. A repeated entry is still aDataError, known or not.verify()with asaltLengthof 2^31 or more isfalse, like any other salt length that the signature does not have. It was anOperationError.pkcs8with the whole point.The shape of a few results
getCipherInfo()returns an object without a prototype that always has Node's six properties, in Node's order. One that does not apply isundefined.kty,crv,x,d.crypto.getRandomValues.nameis"getRandomValues".new X509Certificate()throws Node'sERR_INVALID_ARG_TYPEfor what is neither a string nor bytes.

Where Bun and Node both accept a name, the results are the same, and no name that worked before is refused now.
