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).
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`.
- 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
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
Make all `read*` functions accept an options object, so that we can add config
options to them later (for #1166). This is necessary so that we can remove the
global `openpgp.config`, which doesn't work that well when importing
individual functions.
Furthermore, merge `readMessage` and `readArmoredMessage` into one function,
et cetera.
- `openpgp.generateKey` now expects `userIds` in object format
(strings are no longer supported)
- Remove `util.parseUserId` and `util.formatUserId`
- Replace `UserIDPacket#format` with `UserIDPacket.fromObject`
- Changes `openpgp.generateKey` to accept an explicit `type` parameter,
instead of inferring its value from the `curve` or `rsaBits` params
- Introduces `config.minRsaBits` to set minimum key size of RSA key generation
- Remove the boolean return value of various internal functions that throw on
error (the returned value was unused in most cases)
- Update and fix type definitions
