Trait dbl::Dbl

pub trait Dbl {
    fn dbl(self) -> Self;
    fn inv_dbl(self) -> Self;
}

Double and inverse double over GF(2^n). WARNING: block must be aligned!

This trait is implemented for 64, 128 and 256 bit block sizes. Big-endian order is used.

Required Methods

fn dbl(self) -> Self

Double block. (alternatively: multiply block by x)

If most significant bit of the block equals to zero will return block<<1, otherwise (block<<1)^C, where C is the non-leading coefficients of the lexicographically first irreducible degree-b binary polynomial with the minimal number of ones.

fn inv_dbl(self) -> Self

Reverse double block. (alternatively: divbide block by x)

If least significant bit of the block equals to zero will return block>>1, otherwise (block>>1)^(1<<n)^(C>>1)
