Blake2s Solidity Implementation

This repository contains a Solidity implementation of the BLAKE2s cryptographic hash function, as specified in RFC 7693. The Blake2s.sol contract provides functions to compute BLAKE2s hashes within Ethereum smart contracts.

Features

• Solidity implementation of BLAKE2s hash function.
• Functions for hashing data and converting the result to bytes32.
• Implemented in Solidity 0.8.20
• Fuzz tested

Getting Started

To use this repository, clone it to your local machine and follow the instructions below to integrate the BLAKE2s contract into your project.

Installation

1. Install dependencies yarn install
2. Run tests yarn test

Usage

pragma solidity 0.8.20;

import {Blake2s} from "blake2s-solidity/contracts/Blake2s.sol";

contract MyContract {
    function hash() public pure returns (bytes32) {
        bytes memory input = "foo";
        bytes32 hash = Blake2s.toBytes32(input);
        //0x08d6cad88075de8f192db097573d0e829411cd91eb6ec65e8fc16c017edfdb74
        return hash;
    }
}
