reasonably fast zero-dependency pure-js tripcode implementation based on these projects:

• tripcode tester by NoneGiven
• jcrypt.java by John F. Dumas

correctness

generated tripcodes should match those on 4chan, but please open an issue if you find one that differs

usage

it's really simple

import {tripcode} from "better-tripcode";

const pass = "password";
const trip = tripcode(pass);

console.log("#%s -> !%s", pass, trip);
