Struct Key 

pub struct Key { /* private fields */ }

A key to use for CMAC signing.

Implementations

impl Key

pub fn generate(algorithm: Algorithm) -> Result<Self, Unspecified>

Generate a CMAC signing key using the given algorithm with a random value.

Errors

error::Unspecified if random generation or key construction fails.

pub fn new(algorithm: Algorithm, key_value: &[u8]) -> Result<Self, Unspecified>

Construct a CMAC signing key using the given algorithm and key value.

key_value should be a value generated using a secure random number generator or derived from a random key by a key derivation function.

Errors

error::Unspecified if the key length doesn’t match the algorithm or if CMAC context initialization fails.

pub fn algorithm(&self) -> Algorithm

The algorithm for the key.
