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.
- Make fingerprint and key ID computation async, and rely on Web Crypto
for hashing if available
- Always set fingerprint and keyID on key parsing / generation
- Introduce `*KeyPacket.computeFingerprint()` and
`*KeyPacket.computeFingerprintAndKeyID()`
- Change `getKeyID` and `getFingerprint*` functions to return the
pre-computed key ID and fingerprint, respectively
- Make `PublicKeyPacket.read` async
- 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`
Changes:
- Implementation:
- Remove `PacketList.prototype.concat` and `push`
(we solely rely on `Array.push` instead)
- Fix https://github.com/openpgpjs/openpgpjs/issues/907 by
correctly handling result of `filterByTag`
- Implement `write()` method for `Trust` and `Marker` packets,
to make them compatible with the `BasePacket` interface
- Types:
- Simplify and updated `PacketList` type definitions
- Fix types for `Packet.tag`, which is `static` since
https://github.com/openpgpjs/openpgpjs/pull/1268
- Prevent passing SubkeyPackets where KeyPackets are expected,
and vice versa
To encrypt/decrypt a key, the top-level functions `openpgp.encryptKey` and
`openpgp.decryptKey` should be used instead: these don't mutate the key;
instead, they either return a new encrypted/decrypted key object or throw an
error.
With `Key.prototype.encrypt` and `decrypt`, which mutated the key, it was
possible to end up in an inconsistent state if some (sub)keys could be
decrypted but others couldn't, they would both mutate the key and throw an
error, which is unexpected.
Note that the `keyID` parameter is not supported by `encryptKey`/`decryptKey`,
since partial key decryption is not recommended. If you still need to decrypt
a single subkey or primary key `k`, you can call `k.keyPacket.decrypt(...)`,
followed by `k.keyPacket.validate(...)`. Similarly, for encryption, call
`k.keyPacket.encrypt(...)`.
Additionally, `openpgp.generateKey` now requires `options.userIDs` again,
since otherwise the key is basically unusable. This was a regression from v4,
since we now allow parsing keys without user IDs (but still not using them).
When unencrypted secret key packets are serialized, a 2-byte checksum is
appended after the key material. According to rfc4880bis, these 2 bytes are
not included in the length of the key material (this encoded length is a new
addition of rfc4880bis, specific to v5 keys). We erroneously included them,
causing other implementations to fail to parse unencrypted v5 private keys
generated by OpenPGP.js.
If `expectSigned` is set:
- `openpgp.decrypt` throws immediately if public keys or signatures are
missing, or if the signatures are invalid and streaming is not used.
- `openpgp.verify` throws immediately if signatures are missing, or if the
signatures are invalid and streaming is not used.
- If the signatures are invalid and streaming is used, reading the returned
data stream will eventually throw.
- 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)
* Rename `config.ignoreMdcError` to `config.allowUnauthenticatedMessages`
* Do not support creating sym. enc. messages without integrity protection
* Use `config.aeadProtect` to determine SKESK encryption mode
Keyring handling and storage should be handled in the application, as
localStorage may not meet the durability requirements of the
application, for example.
