node:crypto, webcrypto: a third batch of Node compatibility fixes - #47591
A third batch of independent node:crypto / WebCrypto fixes found by diffing Bun against Node, following #47559 and #47567. Every behaviour below was compared with Node v26.12.1.
Cipher
cipher.update() and cipher.final() call EVP_CipherUpdate_ex and EVP_CipherFinal_ex2, which are told how much room the output has. They called EVP_CipherUpdate and EVP_CipherFinal_ex, which take no size. update() gets the room it needs from EVP_CIPHER_CTX_max_next_update. final() writes at most two blocks, into an array on the stack.
update() reads the input's address and length once.
The result's ArrayBuffer is as long as the result, like Node's.
Deleted: the branch of update() for key-wrap ciphers. BoringSSL has none.
Random
crypto.getRandomValues() always fills the view with RAND_bytes, which is what Node fills it with. Views of 256 bytes or less were filled from the cache of random bytes that randomUUID() draws from. With 1.4.4 on an AMD EPYC, a 16-byte view takes 22 ns from the cache, and the calls that already go to RAND_bytes take 550 to 580 ns (randomFillSync() with 16 bytes, getRandomValues() with 257). Node takes about 740 ns.
It converts its argument the way Web IDL converts to an ArrayBufferView, before it looks at the element type. An ArrayBuffer, a SharedArrayBuffer or anything else that is not a view is a TypeError with codeERR_INVALID_ARG_TYPE, where it was a TypeMismatchError. The message is Node's. A view on a SharedArrayBuffer or on a resizable ArrayBuffer is still filled. The specification refuses one, and so does Node since v26.11.0, though randomFillSync() fills one in both. A call with no argument is ERR_MISSING_ARGS, from bindgen's requiredArguments, with bindgen's message: The "array" argument must be specified.
Deleted: random_data() in Crypto.rs, which chose between the cache and RAND_bytes.
Diffie-Hellman
diffieHellman.computeSecret() calls DH_compute_key_padded, which writes the secret at its full length. It called DH_compute_key and then put the leading zeros back. The result is the same.
RSA
publicEncrypt() and privateDecrypt() take mgf1Hash, which Node added in v26.8.0. It was ignored, so { oaepHash: "sha256", mgf1Hash: "sha1" } used SHA-256 for MGF1, and neither an unknown digest nor a non-string was an error. privateEncrypt() and publicDecrypt() validate it too and then refuse it, as in Node.
With a padding other than OAEP, publicEncrypt() and privateDecrypt() ignore oaepHash, mgf1Hash and oaepLabel, like Node. OpenSSL ignores them there and BoringSSL refuses them, so oaepHash and oaepLabel threw.
A wrong type for one of the three is reported under Node's name for it: key.oaepHash, where it was options.oaepHash.
node:crypto reads an RSA JWK the way Node's ImportJWKRsaKey does:
The JWK decides whether it is a private key, so createPublicKey() and the functions that take a key make the same checks as createPrivateKey().
A private one needs the n that is p times q. subtle.importKey("jwk") checks this too. Neither compared them.
One with oth is rejected. BoringSSL has no multi-prime RSA. node:crypto ignored the member, and subtle.importKey("jwk") accepted an empty array.
Every failure is ERR_CRYPTO_INVALID_JWK. A member that is missing or not a string was ERR_INVALID_ARG_TYPE.
Deleted: the loop in CryptoKeyRSA::importJwk() that decoded oth.
X509Certificate
x509.checkIP() throws ERR_INVALID_ARG_VALUE for a string with a NUL in it, like Node.
WebCrypto
subtle.deriveBits() takes its length as an [EnforceRange] unsigned long, like Node. NaN derived 0 bits and 2 ** 32 + 64 derived 64. Both are now a TypeError. It has WebCore's message and no code.
An EC private key imported from a PKCS#8 structure without the optional public key is exported with it, like Node. BoringSSL remembers that the key came without one, so exportKey("pkcs8") encodes a copy of the key without that flag, as ncrypto's Ec::ExportPrivatePkcs8 does. KeyObject.from(key).export() still gives the key as it came, as in Node.
The SyntaxError for bad or empty keyUsages, or for an extractable HKDF or PBKDF2 key, from SubtleCrypto and from keyObject.toCryptoKey(), is a DOMException with code 12, as in Node and the specification. It was JavaScript's own SyntaxError, which is what ExceptionCode::SyntaxError becomes everywhere in Bun. That mapping is unchanged. These two call createDOMExceptionObject(), which is the default: arm of createDOMException() moved into a function of its own.
getCipherInfo
crypto.getCipherInfo() validates keyLength and ivLength as unsigned 32-bit integers and names them options.keyLength and options.ivLength, like Node. { keyLength: -1 } returned undefined and, for a GCM cipher, { ivLength: -1 } returned the cipher's info with ivLength: -1.
ncrypto.cpp
From upstream:
EVPKeyCtxPointer::setRsaMgf1Md() (ncrypto.cc#L6588), CipherParams::mgf1_digest and its use in CipherImpl() (#L6834).
Rsa::checkPrimeProduct() (#L7099), with two differences that are marked in the file. It has no loop over getOtherPrimeInfos(), which this fork does not have and which is empty with BoringSSL. It returns false without multiplying for a modulus above OPENSSL_RSA_MAX_MODULUS_BITS, which BoringSSL refuses to use, or a factor that is longer than the modulus.
Not from upstream, and marked as such in the file: DH_compute_key_padded.
How did you verify your code works?
Tests, run on a debug + ASAN build, also with BUN_JSC_validateExceptionChecks=1. The new ones 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 two getRandomValues() rows for a view on shared and on resizable memory pass on both.
Test file

test/js/node/test/parallel/test-webcrypto-random.js takes the hunk of Node v26.12.1's version that expects the TypeError.
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.
Same script under this branch, 1.4.4 and Node v26.12.1:
24 ciphers, 16 ways of splitting the input, both directions, padding on and off (1,469 rows). The bytes, the length of each chunk and the errors are those of 1.4.4. For the 19 ciphers that Node's OpenSSL will create, they are also Node's, up to the name of one error code.
13,440 random sequences of update(), setAutoPadding() and final() over 32 cipher names, both directions. The 10,080 that use a cipher Node's OpenSSL will create give Node's bytes, chunk lengths and ArrayBuffer lengths, and fail where Node fails.
1,200 Diffie-Hellman secrets from fixed keys in modp5 and modp14, two of them with a leading zero byte, hash to the same digest under this branch, 1.4.4 and Node.
36 combinations of oaepHash and mgf1Hash give Node's result, and each runtime decrypts the other's ciphertext.
The three OAEP options, under three paddings, in the four functions (36 rows): Bun accepts and refuses what Node does, except that privateDecrypt() refuses RSA_PKCS1_PADDING whatever the options.
33 RSA JWKs through createPrivateKey, createPublicKey and publicEncrypt give Node's result or error code, up to the name of one BoringSSL error. Eleven malformed ones and a valid public one through createPrivateKey, createPublicKey, sign and verify give Node's code and message in 47 of 48 cases. The other is sign() with a public JWK, which both refuse.
cipher.update() and cipher.final() ask BoringSSL for the most the call can
write and tell it how much room the output has. update() reads the input's
address and length once. The result's ArrayBuffer is as long as the result,
like Node's.

It writes the secret at its full length, so computeSecret() no longer moves
the bytes and writes the leading zeros back. The result is the same.

…ke Web IDL
The view is filled with RAND_bytes whatever its length, like Node. Views of
256 bytes or less were filled from the cache that randomUUID() draws from.
The argument is converted to an ArrayBufferView before its element type is
looked at. What is not a view is a TypeError (ERR_INVALID_ARG_TYPE), and so is
a view on a SharedArrayBuffer or on a resizable ArrayBuffer.
node:wasi's random_get fills an array of its own and copies it into the
instance's memory, which can be shared.

Node added the option in v26.8.0. It names the digest of RSA-OAEP's MGF1,
which is oaepHash unless it is given. Bun ignored it.
Co-authored-by: dylanc <dylanc@anthropic.com>
Like Node, which also names them options.keyLength and options.ivLength. A
negative keyLength returned undefined, and a negative ivLength was returned as
the IV length of a GCM cipher.
Co-authored-by: dylanc <dylanc@anthropic.com>
Like Node, createPrivateKey() and subtle.importKey("jwk") compare n with the
product of p and q (ncrypto's Rsa::checkPrimeProduct). BoringSSL has no
multi-prime RSA, so a JWK with oth is invalid.
In node:crypto the JWK decides whether it is a private key, as in Node's
ImportJWKRsaKey, so createPublicKey() and the functions that take a key make
the same checks.

… DOMException
- subtle.deriveBits() takes its length as an [EnforceRange] unsigned long, like
Node. NaN derived 0 bits and 2 ** 32 + 64 derived 64.
- An EC private key imported from a PKCS#8 structure without the optional
public key is exported with it.
- The SyntaxError for bad or empty keyUsages, from SubtleCrypto and from
keyObject.toCryptoKey(), is a DOMException.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The changes update Node crypto cipher options and output handling, RSA JWK validation, Web Crypto argument and key handling, random-value validation, and two crypto primitives. Tests cover the updated APIs and validation cases.
Changes
Random-value handling
Layer / File(s)
Summary
Random-value validation and filling src/runtime/webcore/Crypto.bind.ts, src/runtime/webcore/Crypto.rs, src/jsc/rare_data.rs, test/js/node/test/parallel/test-webcrypto-random.js, test/js/web/crypto/web-crypto.test.ts, test/js/web/web-globals.test.js
The binding changes required-argument handling, input validation, and random-byte filling. Tests update argument and view coverage; EntropyCache::SIZE becomes crate-visible.
Cipher parameters carry an optional MGF1 digest. rsaFunction resolves mgf1Hash and passes it to OpenSSL. Tests cover digest combinations, padding, and invalid options.
Cipher update and final output src/jsc/bindings/node/crypto/JSCipherPrototype.cpp
Cipher update and finalization use bounded output buffers and return the bytes written. CCM decipher authentication handling remains.
DHPointer::computeSecret uses DH_compute_key_padded and returns an empty result for a negative return value.
X.509 IP name validation
Layer / File(s)
Summary
NUL-containing IP names src/jsc/bindings/JSX509Certificate.cpp
checkIP returns INVALID_NAME for a NUL-containing string.

update() and final() call EVP_CipherUpdate_ex and EVP_CipherFinal_ex2

final() writes at most two blocks, into an array on the stack. The branch
of update() for key-wrap ciphers goes: BoringSSL has none.

Every member is read once, and a member that is missing or not a string is
ERR_CRYPTO_INVALID_JWK like every other failure, whichever function was

BoringSSL refuses to use, or a factor that is longer than the modulus.

With a padding other than OAEP, publicEncrypt() and privateDecrypt() ignore
oaepHash, mgf1Hash and oaepLabel, as they do in Node. OpenSSL ignores them
there and BoringSSL refuses them. A wrong type is reported as key.oaepHash,
key.mgf1Hash or key.oaepLabel, which are Node's names.
oaepHash and mgf1Hash are read by one function. Node's own test of mgf1Hash
is added as it is, with the two helpers of test/common/crypto.js it needs.

Validate CRT values on private RSA JWK import.
1464-1464: Minor · Functional Correctness · Quick win
Validate CRT values on private RSA JWK import.
The import checks only n == p * q. It does not check dp, dq, or qi. A JWK with valid n, p, and q but incorrect CRT values imports successfully. Later private-key operations then fail, because BoringSSL verifies the CRT result and returns an error. This gap predates the PR. Check dp, dq, and qi against d, p, and q before creating the key.

random_get calls dest.set, chunk.subarray, and crypto.getRandomValues. These are ordinary user-overridable methods. If host code replaces Uint8Array.prototype.set with a no-op, random_get still returns WASI_ESUCCESS and the guest range stays unchanged.

The fill creates a &mut [u8] over a SharedArrayBuffer that another worker can write during the call.
19-19: Minor · Stability & Availability · Poor tradeoff
The fill creates a &mut [u8] over a SharedArrayBuffer that another worker can write during the call.
get_random_values accepts views on shared memory and passes array_buffer.byte_slice_mut() to rand_bytes. The synchronous call blocks same-thread resizing. It does not block writes from another worker. A cross-worker write during the fill is a data race under Rust's rules, and it violates the exclusivity of the &mut [u8]. The bytes that remain depend on the interleaving, and Rust treats the access as undefined behavior.
A fix changes either the accepted input set or the fill design. Excluding shared views conflicts with the stated Node-compatible intent. Documenting concurrent writes does not remove the race. No safe code change is established here.

Review comment at @src/runtime/webcore/Crypto.rs at line 19:
Update get_random_values so filling a SharedArrayBuffer-backed view never
creates or passes an exclusive &mut [u8] through byte_slice_mut to rand_bytes.
Use a memory-access design safe against concurrent worker writes while
preserving support for shared views.

### 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()` 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. oven-sh/boringssl#16 adds the seven rows,
and this moves the pin to the commit that merged it.
oven-sh/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()`](https://github.com/nodejs/node/blob/v26.12.1/lib/internal/crypto/util.js#L229-L251)
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
`KeyObject`s. 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`](https://github.com/nodejs/node/blob/v26.12.1/src/crypto/crypto_ec.cc#L550)
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](https://github.com/nodejs/node/blob/v26.12.1/lib/internal/crypto/hash.js#L323-L391),
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()`](https://github.com/nodejs/node/blob/v26.12.1/lib/internal/crypto/util.js#L1222-L1251)
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.
oven-sh/boringssl#16 has its own test in `rsa_test.cc`.

…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`.

What does this PR do?
A third batch of independent
node:crypto/ WebCrypto fixes found by diffing Bun against Node, following #47559 and #47567. Every behaviour below was compared with Node v26.12.1.Cipher
cipher.update()andcipher.final()callEVP_CipherUpdate_exandEVP_CipherFinal_ex2, which are told how much room the output has. They calledEVP_CipherUpdateandEVP_CipherFinal_ex, which take no size.update()gets the room it needs fromEVP_CIPHER_CTX_max_next_update.final()writes at most two blocks, into an array on the stack.update()reads the input's address and length once.ArrayBufferis as long as the result, like Node's.update()for key-wrap ciphers. BoringSSL has none.Random
crypto.getRandomValues()always fills the view withRAND_bytes, which is what Node fills it with. Views of 256 bytes or less were filled from the cache of random bytes thatrandomUUID()draws from. With 1.4.4 on an AMD EPYC, a 16-byte view takes 22 ns from the cache, and the calls that already go toRAND_bytestake 550 to 580 ns (randomFillSync()with 16 bytes,getRandomValues()with 257). Node takes about 740 ns.ArrayBufferView, before it looks at the element type. AnArrayBuffer, aSharedArrayBufferor anything else that is not a view is aTypeErrorwithcodeERR_INVALID_ARG_TYPE, where it was aTypeMismatchError. The message is Node's. A view on aSharedArrayBufferor on a resizableArrayBufferis still filled. The specification refuses one, and so does Node since v26.11.0, thoughrandomFillSync()fills one in both.

The 10,080 that use a cipher Node's OpenSSL will create give Node's bytes, chunk lengths andArrayBufferlengths, and fail where Node fails.modp5andmodp14, two of them with a leading zero byte, hash to the same digest under this branch, 1.4.4 and Node.oaepHashandmgf1Hashgive Node's result, and each runtime decrypts the other's ciphertext.privateDecrypt()refusesRSA_PKCS1_PADDINGwhatever the options.createPrivateKey,createPublicKeyandpublicEncryptgive Node's result or error code, up to the name of one BoringSSL error. Eleven malformed ones and a valid public one throughcreatePrivateKey,createPublicKey,signandverifygive Node's code and message in 47 of 48 cases. The other issign()with a public JWK, which both refuse.Generated by Claude Code
