Implementations

impl HMAC

pub fn mac(self, data: &[u8], key: &Key) -> Vec<u8>

Produces an HMAC tag using the section of the key material reserved for integrity verification.

Panics

Will panic if the user has selected an algorithm for which support has not been compiled in.

pub fn id(self, data: &[u8], key: &Key) -> Vec<u8>

Produces an HMAC tag using the section of the key material reserved for ChunkID generation.

Panics

Will panic if the user has selected an algorithm for which support has not been compiled in.

pub fn verify_hmac(self, input_mac: &[u8], data: &[u8], key: &Key) -> bool

Produces an HMAC for the supplied data, using the portion of the supplied key reserved for integrity verification, and the algorithm specified by the variant of self, and verifies it against the supplied HMAC, using constant time comparisons where possible.

Panics

Panics if the user has selected an algorithm for which support has not been compiled in.

Trait Implementations
