Jack Grigg	999dcbfcab	Migrate to blake2b_simd and blake2s_simd crates ... The primary reason for migrating is that these crates provide APIs for setting the personalisation string. This enables us to depend solely on published crates, and thus publish our own crates. The SIMD implementations are ported from libsodium. Closes #67.	2019-07-10 13:12:14 -04:00

Jack Grigg	060977fe54	Return edwards::Point from sapling_ka_agree ... This matches how sapling_ka_agree and kdf_sapling are defined in the protocol spec. kdf_sapling also now takes ownership of dhsecret to discourage use of the sapling_ka_agree output elsewhere.	2019-06-06 13:38:33 +01:00

Jack Grigg	6dcb4040af	Switch to crypto_api_chachapoly crate ... This crate exposes both the ChaCha20Poly1305 IETF construction, and the underlying ChaCha20 IETF primitive, removing the need for depending on our own fork of the previous chacha20-poly1305-aead crate.	2019-04-11 06:33:41 -07:00
