pub struct Context { /* private fields */ }Expand description
A context for multi-step (Init-Update-Finish) HMAC signing.
Use sign for single-step HMAC signing.
Implementations
sourceimpl Context
impl Context
sourcepub fn with_key(signing_key: &Key) -> Self
pub fn with_key(signing_key: &Key) -> Self
Constructs a new HMAC signing context using the given digest algorithm and key.
sourcepub fn update(&mut self, data: &[u8])
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.
sourcepub fn sign(self) -> Tag
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.
