Struct Blake2bKeyed 

pub struct Blake2bKeyed { /* private fields */ }

BLAKE2b keyed-hash (MAC mode), with variable output size 1–64 bytes.

BLAKE2b in keyed mode is a one-pass MAC: the key is absorbed as the first block. Keys must be between 1 and 64 bytes inclusive.

Implementations

impl Blake2bKeyed

pub fn new(key: &[u8]) -> Result<Self, CryptoError>

Create a keyed BLAKE2b hasher.

Errors

Returns CryptoError::InvalidKey if key is empty or longer than 64 bytes.

pub fn hash(&self, msg: &[u8], out: &mut [u8]) -> Result<(), CryptoError>

Hash msg under this key; output is written to out.

out.len() must be between 1 and 64 bytes inclusive.

Errors

Returns CryptoError::BadInput if out is empty or longer than 64 bytes. Returns CryptoError::InvalidKey if the key is invalid (should not happen after successful new).
