Jack Grigg fdb6e208db Check note plaintext version byte when decrypting 2019-06-06 13:38:34 +01:00
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.

Jack Grigg 34658c4bd3 Raise minimum Rust version to 1.32 
The crypto_api_chachapoly uses two new features introduced in 1.32:

- Self struct constructors
- u64::to_le_bytes()
 2019-04-11 06:41:22 -07:00
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.

Jack Grigg bbec1b841d Use slices of native strings to pass parameter paths into Rust 
On Windows, the slices are [u16] representing UTF-16. On all other
platforms, the slices are [u8] in the native filesystem encoding.

Closes #44.
