A toolbox to compute MiMC hash in Javascript, which allows to export a .zok file to perform the same computation in ZoKrates.
Table of contents
Getting Started
To install the library, run:
$ npm install mimcjs
Usage
Computing MiMC Hash
const mimcjs = require('mimcjs')
const point1 = [1,2]
const point2 = [123,"0x55DC2CF4057e4D6D78eE7Ea5170B58c04D2c08a7"]
var hash1 = mimcjs.mimc(point1)
var hash2 = mimcjs.mimc(point2)
CLI
Some commands are available from CLI:
mimc help
show commandsmimc hash <point>
perform MiMC hash on a pointmimc generate-constants <seed>
generate round constants starting from a seed (number or string)mimc set-rounds <rounds>
set DEFAULT_ROUNDS parametermimc set-exponent <exponent>
set DEFAULT_EXPONENT parametermimc export-circuit
export a .zok program to compute MiMC hash in ZoKrates using default parameters ROUND_CONSTANTS and DEFAULT_ROUNDS
