Breaking change: the requirements of `config.minRSABits`, `rejectPublicKeyAlgorithms` and `rejectCurves`
are now applied to the primary key, aside from the selected subkey.
The motivation is that the subkeys are certified by the primary key, but if the latter is
weak, arbitrary subkeys could potentially be added.
Note that the change does not affect decryption, to allow decrypting older messages.
Breaking change: the `config.deflateLevel` is removed as the API does not accept a deflate level
in input, and the setting is of limited importance. Plus, using compression
is discouraged on security grounds.
The latest crypto refresh specifies an HKDF step to be used for
deriving the key to encrypt the session key with.
It also specifies two additional length fields.
Mocha v10 requires the lib to be esm compliant.
ESM mandates the use of file extensions in imports, so to minimize the
changes (for now), we rely on the flag `experimental-specifier-resolution=node`
and on `ts-node` (needed only for Node 20).
Breaking changes:
downstream bundlers might be affected by the package.json changes depending on
how they load the library.
NB: legacy package.json entrypoints are still available.
Set to replace `enums.curve.ed25519` (resp. `.curve25519`), which can still be used everywhere,
but it will be dropped in v6.
Deprecation notices have been added to ease transition.
Set to replace `enums.publicKey.eddsa`, which can still be used everywhere,
but it will be dropped in v6.
Deprecation notices have been added to ease transition.
When parsing errors are being ignored, packets that fail to parse are now
included in the resulting packet list as `UnparseablePacket`s . This way, when
parsing keys that contain unparsable (sub)key, we avoid associating the
following non-key packets to the wrong key entity.
On serialization, `UnparseablePacket`s are also included by writing their raw
packet body as it was read.
In several packet classes, we used to store string identifiers for public-key,
aead, cipher or hash algorithms. To make the code consistent and to avoid
having to convert to/from string values, we now always store integer values
instead, e.g. `enums.symmetric.aes128` is used instead of `'aes128'`.
This is not expected to be a breaking change for most library users. Note that
the type of `Key.getAlgorithmInfo()` and of the session key objects returned
and accepted by top-level functions remain unchanged.
Affected classes (type changes for some properties and method's arguments):
- `PublicKeyPacket`, `PublicSubkeyPacket`, `SecretKeyPacket`,
`SecretSubkeyPacket`
- `SymEncryptedIntegrityProtectedDataPacket`, `AEADEncryptedDataPacket`,
`SymmetricallyEncryptedDataPacket`
- `LiteralDataPacket`, `CompressedDataPacket`
- `PublicKeyEncryptedSessionKey`, `SymEncryptedSessionKeyPacket`
- `SignaturePacket`
Other potentially breaking changes:
- Removed property `AEADEncryptedDataPacket.aeadAlgo`, since it was redudant
given `.aeadAlgorithm`.
- Renamed `AEADEncryptedDataPacket.cipherAlgo` -> `.cipherAlgorithm`
Breaking changes:
- throw error on key generation if the requested public key algorithm is
included in `config.rejectPublicKeyAlgorithms`;
- add `config.rejectCurves` to blacklist a set of ECC curves, to prevent keys
using those curves from being generated, or being used to
encrypt/decrypt/sign/verify messages.
By default, `config.rejectCurves` includes the brainpool curves
(`brainpoolP256r1`, `brainpoolP384r1`, `brainpoolP512r1`) and the Bitcoin curve
(`secp256k1`). This is because it's unclear whether these curves will be
standardised[1], and we prefer to blacklist them already, rather than introduce
a breaking change after release.

Breaking change: passing non-existing configuration options to top-level
functions now results in an error, to make users aware that the given
configuration cannot be applied.
Configuration options related to parsing have been changed to make it possible
to try to read messages containing malformed packets. Changes:
- rename `config.tolerant` to `config.ignoreUnsupportedPackets`. This still
defaults to `true`.
- Add `config.ignoreMalformedPackets` to ignore packets that fail to parse
(when possible). This option was not available before and it defaults to `false`.
Breaking changes:
- a new `format` option has been added to `openpgp.encrypt`, `sign` and
`encryptSessionKey` to select the format of the output message. `format`
replaces the existing `armor` option, and accepts three values:
* if `format: 'armor'` (default), an armored signed/encrypted message is
returned (same as `armor: true`).
* if `format: 'binary'`, a binary signed/encrypted message is returned (same
as `armor: false`).
* if `format: 'object'`, a Message or Signature object is returned (this was
not supported before).
This change is to uniform the output format selection across all top-level
functions (following up to #1345).
- All top-level functions now throw if unrecognised options are passed, to make
library users aware that those options are not being applied.
This change is to make the code more consistent between the streaming and
non-streaming cases.
The validity of a signature (or the corresponding verification error) can be
determined through the existing `verified` property.
- `openpgp.generateKey`, `reformatKey` and `revokeKey` take a new `format`
option, whose possible values are: `'armor', 'binary', 'object'` (default is
`'armor'`).
- `generateKey` and `reformatKey` now return an object of the form `{
publicKey, privateKey, revocationCertificate }`, where the type of `publicKey`
and `privateKey` depends on `options.format`:
* if `format: 'armor'` then `privateKey, publicKey` are armored strings;
* if `format: 'binary'` then `privateKey, publicKey` are `Uint8Array`;
* if `format: 'object'` then `privateKey, publicKey` are `PrivateKey` and
`PublicKey` objects respectively;
- `revokeKey` now returns `{ publicKey, privateKey }`, where:
* if a `PrivateKey` is passed as `key` input, `privateKey, publicKey` are of the
requested format;
* if a `PublicKey` is passed as `key` input, `publicKey` is of the requested format,
while `privateKey` is `null` (previously, in this case the `privateKey` field
was not defined).
Breaking changes:
- In `revokeKey`, if no `format` option is specified, the returned `publicKey,
privateKey` are armored strings (they used to be objects).
- In `generateKey` and `reformatKey`, the `key` value is no longer returned.
- For all three functions, the `publicKeyArmored` and `privateKeyArmored`
values are no longer returned.
- When parsing, throw on unexpected packets even if `config.tolerant = true`
(e.g. if a Public Key packet is found when reading a signature).
- Always ignore Trust and Marker packets on parsing.
- Fix#1145: correctly verify signatures that include Marker packets when
`config.tolerant = false`.
- Rename `publicKeys` to `encryptionKeys` or `verificationKeys` depending on their use
- Rename `privateKeys` to `decryptionKeys` or `signingKeys` depending on their use
- Similarly, rename `toUserIDs` to `encryptionUserIDs` and `fromUserIDs` to `signingUserIDs`
Don't ignore parse errors if `config.tolerant` is enabled. This leads to
more useful error messages in most cases, as ignoring these errors will
most likely still lead to an error down the line (e.g. if a key binding
signature is missing). Unsupported and unknown packets and packets with
an unsupported or unknown version are still ignored, for forward
compatibility.
Also, make `PKESK.encrypt`/`decrypt` void.
- Add `PacketList.fromBinary` which parses binary data and returns a
`PacketList`. Using it instead of `PacketList.read` avoids being left
with partially read data in case of errors.
- Rename `toPacketlist` to `toPacketList` in `Key`, `Subkey` and `User`
classes
- In `readMessage`, pass down `config` to `PacketList.read`
- Add `config` param to `CompressedDataPacket.decompress`,
`AEADEncryptedDataPacket.decrypt` and `Message.appendSignature`
- Use PascalCase for classes, with uppercase acronyms.
- Use camelCase for function and variables. First word/acronym is always
lowercase, otherwise acronyms are uppercase.
Also, make the packet classes' `tag` properties `static`.
- Add `config.rejectPublicKeyAlgorithms` to disallow using the given algorithms
to verify, sign or encrypt new messages or third-party certifications.
- Consider `config.minRsaBits` when signing, verifying and encrypting messages
and third-party certifications, not just on key generation.
- When verifying a message, if the verification key is not found (i.e. not
provided or too weak), the corresponding `signature` will have
`signature.valid=false` (used to be `signature.valid=null`).
`signature.error` will detail whether the key is missing/too weak/etc.
Generating and verifying key certification signatures is still permitted in all cases.
- Rename `config.compression` to `config.preferredCompressionAlgorithm`
- Rename `config.encryptionCipher` to `config.preferredSymmetricAlgorithm`
- Rename `config.preferHashAlgorithm` to `config.preferredHashAlgorithm`
- Rename `config.aeadMode` to `config.preferredAeadAlgorithm`
- When encrypting to public keys, the compression/aead/symmetric algorithm is selected by:
- taking the preferred algorithm specified in config, if it is supported by all recipients
- otherwise, taking the "MUST implement" algorithm specified by rfc4880bis
- When encrypting to passphrases only (no public keys), the preferred algorithms from `config` are always used
- EdDSA signing with a hash algorithm weaker than sha256 is explicitly disallowed (https://tools.ietf.org/id/draft-ietf-openpgp-rfc4880bis-10.html#section-15-7.2)
Refactor functions to take the configuration as a parameter.
This allows setting a config option for a single function call, whereas
setting `openpgp.config` could lead to concurrency-related issues when
multiple async function calls are made at the same time.
`openpgp.config` is used as default for unset config values in top-level
functions.
`openpgp.config` is used as default config object in low-level functions
(i.e., when calling a low-level function, it may be required to pass
`{ ...openpgp.config, modifiedConfig: modifiedValue }`).
Also,
- remove `config.rsaBlinding`: blinding is now always applied to RSA decryption
- remove `config.debug`: debugging mode can be enabled by setting
`process.env.NODE_ENV = 'development'`
- remove `config.useNative`: native crypto is always used when available
