Struct ring::digest::Context [−][src]
A context for multi-step (Init-Update-Finish) digest calculations.
Examples
use ring::digest; let one_shot = digest::digest(&digest::SHA384, b"hello, world"); let mut ctx = digest::Context::new(&digest::SHA384); ctx.update(b"hello"); ctx.update(b", "); ctx.update(b"world"); let multi_part = ctx.finish(); assert_eq!(&one_shot.as_ref(), &multi_part.as_ref());
Implementations
impl Context
[src]
pub fn new(algorithm: &'static Algorithm) -> Self
[src]
Constructs a new context.
pub fn update(&mut self, data: &[u8])
[src]
Updates the digest with all the data in data
. update
may be called
zero or more times until finish
is called. It must not be called
after finish
has been called.
pub fn finish(self) -> Digest
[src]
Finalizes the digest calculation and returns the digest value. finish
consumes the context so it cannot be (mis-)used after finish
has been
called.
pub fn algorithm(&self) -> &'static Algorithm
[src]
The algorithm that this context is using.
