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').
- Add `PrivateKey` and `PublicKey` classes. A `PrivateKey` can always
be passed where a `PublicKey` key is expected, but not vice versa.
- Unexport `Key`, and export `PrivateKey` and `PublicKey`.
- Rename `Key.packetlist2structure` to `Key.packetListToStructure`.
- Change `Key.update` to return a new updated key, rather than
modifying the destination one in place.
- Add `openpgp.readPrivateKey` and `openpgp.readPrivateKeys` to avoid
having to downcast the result of `readKey(s)` in TypeScript.
- 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`.
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.
Instead of as modules.
Replace *.read with read*, *.readArmored with readArmored*, etc.
Replace cleartext.readArmored with readArmoredCleartextMessage.
Replace message.fromText with Message.fromText, etc.
