Struct ring::hmac::SigningContext

source · [−]

pub struct SigningContext { /* private fields */ }

Expand description

A context for multi-step (Init-Update-Finish) HMAC signing.

Use sign for single-step HMAC signing.

Implementations

source

impl SigningContext

source

pub fn with_key(signing_key: &SigningKey) -> SigningContext

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

source

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.

source

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
