Implementations

impl Context

pub fn with_key(signing_key: &Key) -> Self

Constructs a new HMAC signing context using the given digest algorithm and key.

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

Updates the HMAC with all the data in data. update may be called zero or more times until finish is called.

pub fn sign(self) -> Tag

Finalizes the HMAC calculation and returns the HMAC value. sign consumes the context so it cannot be (mis-)used after sign has been called.

It is generally not safe to implement HMAC verification by comparing the return value of sign to a tag. Use verify for verification instead.
