Struct ring::hmac::SigningContext [−][src]
pub struct SigningContext { /* fields omitted */ }
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]
impl SigningContext
pub fn with_key(signing_key: &SigningKey) -> SigningContext
[src]
pub fn with_key(signing_key: &SigningKey) -> SigningContext
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]
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.
C analog: HMAC_Update
pub fn sign(self) -> Signature
[src]
pub fn sign(self) -> Signature
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
