Struct ring::digest::Context[][src]

pub struct Context { /* fields omitted */ }
Expand description

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

Constructs a new context.

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.

Finalizes the digest calculation and returns the digest value. finish consumes the context so it cannot be (mis-)used after finish has been called.

The algorithm that this context is using.
