Crate keccak_prime 

Keccak derived functions specified in FIPS-202, SP800-185 and KangarooTwelve.

Example

let input_a = b"hello world";
let input_b = b"!";
let mut output = [0u8; 32];
hasher.update(input_a);
hasher.update(input_b);
hasher.finalize(&mut output);

Modules

fortuna

This is a simplified implementation of the Fortuna CSPRNG. The main difference from the original Fortuna is that we don’t use hashes for seeding; the hash is computed externally. Instead, we generate a key before the generation of pseudorandom data.

prime

Implements the Keccak-prime function.

sloth

Sloth VDF implementation.

Structs

Buffer

Holds internal Keccak state.

Keccak

The Keccak hash functions defined in Keccak SHA3 submission.

Sha3

The SHA3 hash functions defined in FIPS-202.

Shake

The SHAKE extendable-output functions defined in FIPS-202.

Traits

Hasher

A trait for hashing an arbitrary stream of bytes.

IntoXof

A trait used to convert Hasher into it’s Xof counterpart.

Xof

Extendable-output function (XOF) is a function on bit strings in which the output can be extended to any desired length.
