Implementations

impl<OutSize> Blake2sMac<OutSize>

where OutSize: ArraySize + IsLessOrEqual<U32>, LeEq<OutSize, U32>: NonZero,

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.

Errors

Key length should not be empty or bigger than the block size and the 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.
