[−][src]Struct ring::hmac::SigningContext
A context for multi-step (Init-Update-Finish) HMAC signing.
Use sign for single-step HMAC signing.
C analog: HMAC_CTX.
Methods
impl SigningContext[src]
pub fn with_key(signing_key: &SigningKey) -> SigningContext[src]
Constructs a new HMAC signing context using the given digest algorithm and key.
C analog: HMAC_CTX_init
pub fn update(&mut self, data: &[u8])[src]
Updates the HMAC with all the data in data. update may be called
zero or more times until finish is called.
C analog: HMAC_Update
pub fn sign(self) -> Signature[src]
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
C analog: HMAC_Final
