Expand description
Returns the digest of data
using the given digest algorithm.
Examples:
use ring::{digest, test};
let expected_hex = "09ca7e4eaa6e8ae9c7d261167129184883644d07dfba7cbfbc4c8a2e08360d5b";
let expected: Vec<u8> = test::from_hex(expected_hex).unwrap();
let actual = digest::digest(&digest::SHA256, b"hello, world");
assert_eq!(&expected, &actual.as_ref());
