Struct chaskey::Tag

pub struct Tag(_);

A 128-bit Chaskey tag.

WARNING: This is a wrapper around an [u32; 4] in order to provide constant-time equality comparisons. You may unwrap it if you like, but you need to be very careful what you do with it, or otherwise you may risk a timing attack!

Methods

impl Tag

fn new(words: [u32; 4]) -> Tag

fn raw_words(&self) -> &[u32; 4]

Unwrap a Tag into its raw word array. Performing variable-time comparisons of these arrays may expose you to timing attacks; stick to comparing the Tag wrappers if you can.

fn to_u64(&self) -> u64

fn raw_bytes(&self) -> [u8; 16]
