5c1325ed11 aead: rewrite api
Decouple the authentication tag from the ciphertext and add streaming
interfaces.

Tests will be fixed in the next commit.

9da7685779 aead/{,x}chacha20-poly1305: simplify
Use one-pass interfaces for encryption and decryption and rename the
Poly1305 key setup to the more correct poly1305_keysetup.

2b3e390bbf Make params struct non-const
Upcoming changes will push lc_*_ctx into the params struct for higher
order constructions like HMAC or HKDF.

62eb1ea6f8 aead/chacha20-poly1305: reflect that the keysetup is only for {,X}ChaCha20 2024-06-09 02:21:06 +00:00
d2817487e8 aead/chacha20-poly1305: inline anycrypt
Also use decrypt for the decryption path instead of relying on ChaCha20
using the same stream for encryption and decryption.

a6208487e4 aead: replace init args with implementation-specific params struct
This unbreaks {,X}ChaCha20-Poly1305. Thanks to the use of params, the
{,X}ChaCha20-Poly1305 doesn't need to reach into the guts of ChaCha20
state. Move {en,de}cryption and key setup into its own functions.

This breaks the tests, which will be fixed in the following commit.

52ab9ca179 ct/lc_ct_cmp: improve interface
Return 0xffffffff if arguments compare equal, 0 otherwise. Change all
consumers accordingly.
