Crate kangarootwelve_xkcp

A Rust wrapper around the eXtended Keccak Code Package implementation of the KangarooTwelve cryptographic hash function.

Examples

// Hash an input all at once.
let hash1 = kangarootwelve_xkcp::hash(b"foobarbaz");

// Hash an input incrementally.
let mut hasher = kangarootwelve_xkcp::Hasher::new();
hasher.update(b"foo");
hasher.update(b"bar");
hasher.update(b"baz");
let hash2 = hasher.finalize();
assert_eq!(hash1, hash2);

// Extended output. OutputReader also implements Read.
let mut hasher = kangarootwelve_xkcp::Hasher::new();
hasher.update(b"foobarbaz");
let mut output_reader = hasher.finalize_xof();
let mut output = [0; 1000];
output_reader.squeeze(&mut output);
assert_eq!(&output[..32], hash1.as_bytes());

Structs

Hash	An output of the default size, 32 bytes, which provides constant-time equality checking.
Hasher	An incremental hash state that can accept any number of writes.
OutputReader	An incremental reader for extended output, returned by Hasher::finalize_xof and Hasher::finalize_custom_xof.

Constants

RATE	The number of bytes hashed or output per block.

Functions

hash	Hash a slice of bytes all at once. For multiple writes, the optional customization string, or extended output bytes, see Hasher.
