Implementations

source

impl<OutSize> Blake2bMac<OutSize> where
OutSize: ArrayLength<u8> + IsLessOrEqual<U64>,
LeEq<OutSize, U64>: NonZero,

source

pub fn new_with_salt_and_personal(
 key: &[u8 ],
 salt: &[u8 ],
 persona: &[u8 ]
) -> Result<Self, InvalidLength>

Create new instance using provided key, salt, and persona.

Key length should not be bigger than block size, salt and persona length should not be bigger than quarter of block size. If any of those conditions is false the method will return an error.
