Struct GhashHw 

pub struct GhashHw { /* private fields */ }

GHASH key with the powers H^1..H^8 precomputed for the carry-less multiply path.

Implementations

impl GhashHw

pub fn new(h: &[u8; 16]) -> Option<GhashHw>

h is the hash subkey E(K, 0^128). Returns None if the CPU lacks carry-less multiply.

pub fn update(&self, y: &mut [u8; 16], data: &[u8])

Absorbs data into the GHASH state y (standard byte order). A final partial block is padded with zeros, as GCM requires.
