Trait crypto_mac::Mac

pub trait Mac: Sized {
    type OutputSize: ArrayLength<u8>;
    fn new(key: &[u8]) -> Result<Self, InvalidKeyLength>;
    fn input(&mut self, data: &[u8]);
    fn result(self) -> MacResult<Self::OutputSize>;

    fn verify(self, code: &[u8]) -> Result<(), MacError> { ... }
}

The Mac trait defines methods for a Message Authentication algorithm.

Associated Types

type OutputSize: ArrayLength<u8>

Required Methods

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

Create new MAC instance. DO NOT USE low-entropy keys (e.g. passwords)!

For low-entropy keys first use an appropriate key derivation function (KDF), e.g. argon2, scrypt or PBKDF2

fn input(&mut self, data: &[u8])

Process input data.

fn result(self) -> MacResult<Self::OutputSize>

Obtain the result of a Mac computation as a MacResult.

Provided Methods

fn verify(self, code: &[u8]) -> Result<(), MacError>

Check if code is correct for the processed input
