Keccak SHA3 in Lys

Keccak256 implemented in Lys

Specification at: http://keccak.noekeon.org/specs_summary.html

This implementation is based on https://github.com/axic/keccak-wasm/blob/master/keccak.wast which is also based on https://github.com/rhash/RHash/blob/master/librhash/sha3.c

Objective of this repository

The objective is to provide a "real life" use case for Lys, and gather feedback and ideas from the usage of the tool. As well as detect any kind of gap in the tooling.

This library is not intended to be used in production. This is only a tech preview for Lys

To start with the code please take a look at

• The implementation of keccak src/keccak.lys
• The exposed API src/main.lys
• The glue code for JS src/index.ts

To build locally

Run make build, make sure to have at least Node.js 10 installed.

1. It first builds Lys to the build folder using lys src/main.lys --wast
2. It then uses @zeit/ncc to create a single file using src/index.ts
3. Finally, it performs a sanity test using mocha.
