Hi there! I am just releasing the first version of the Keccak-256 hashing algorithm. https://en.wikipedia.org/wiki/SHA-3 You can find it at: https://github.com/sbragagnolo/Keccak This version is based on a javascript implementation: https://github.com/emn178/js-sha3 This implementation supports as message: bytearray and ascii and utf-8 strings. Soon i will be adding support to the rest of the Keccak family of hashing functions, since the implementations is quite configurable, is just need to add some constructors with specific configurations and tests for this other cases of usage. Here a onliner for building an image with the version v0.1: wget -O- https://raw.githubusercontent.com/sbragagnolo/Keccak/v0.1/build.sh | bash Hope you find it useful :) Santiago
