Instead of calling getPreferredAlgo('symmetric') and
getPreferredAlgo('aead'), we define and call getPreferredCipherSuite()
to determine the preferred symmetric and AEAD algorithm.
Additionally, we remove isAEADSupported(), instead we return
aeadAlgorithm: undefined from getPreferredCipherSuite() if AEAD is not
supported (CFB is used instead).
And finally, we define getPreferredCompressionAlgo() to replace
getPreferredAlgo('compression').
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.
The crypto refresh says that we MUST NOT reject messages where the
CRC24 checksum is incorrect. So, we remove the check for it.
Also, remove the checksumRequired config.
The noble-hashes fork uses the same fallback implementation,
except BN.js is always imported (due to lib contraints), so a dynamic import is now superfluous
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.
In terms of API, this feature is backwards compatible, no breaking changes.
However, since a Wasm module is loaded for the Argon2 computation, browser apps
might need to make changes to their CSP policy in order to use the feature.
Newly introduced config fields:
- `config.s2kType` (defaulting to `enums.s2k.iterated`): s2k to use on
password-based encryption as well as private key encryption;
- `config.s2kArgon2Params` (defaulting to "uniformly safe settings" from Argon
RFC): parameters to use on encryption when `config.s2kType` is set to
`enums.s2k.argon2`;
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.
As specified in openpgp-crypto-refresh-09.
Instead of encoding the symmetric key algorithm in the PKESK ciphertext (requiring padding),
the symmetric key algorithm is left unencrypted.

Such keys are still capable of encryption and signature verification.
This change is relevant for forward compatibility of v4 keys encrypted using e.g. argon2.
Previously, `verifyAllUsers` would fail on keys with User Attributes.
Now, it returns a list of objects that have a either a non-null `userID`
property (in the case of User IDs) or a non-null `userAttribute`
property that contains the User Attribute packet.

This config option allows parsing additional packet types when parsing
a packet list or armored object, in contexts where they are normally
not expected to appear, by passing a list of packet classes
(e.g. `additionalAllowedPackets: [PublicKeyPacket]`).
Most rules are derived from the `airbnb` template.
Some "bad" rule exceptions remain, but they require too many changes to fix, so
we leave it to a future refactoring.
Assign most signature subpacket types a criticality based on whether
failing to interpret their meaning would negatively impact security.
For Notation Data subpackets, let the user indicate their criticality
using the `signatureNotations[*].critical` property.
