                I describe a method for making Lamport signatures take up less space. I haven't seen anyone use hash chains this way before, so I think it's pretty cool.
              
          
    What's this all about?

Digital cryptography! This is a subject I've been interested in since taking a class with Prof. Fred Schneider back in college. Articles pop up on Hacker News fairly often that pique my interest and this technique is the result of one of them.
Specifically, this is about Lamport signatures. There are many signature algorithms (ECDSA and RSA are the most commonly used) but Lamport signatures are unique because they are formed using a hash function. Many cryptographers believe that this makes them resistant to attacks made possible by quantum computers.
How does a Lamport Signature work?
	import axios, { AxiosRequestConfig } from "axios";

	import router from "@/router"; //shortcut to src
	import { Module } from "vuex";

	const authModule: Module<any, any> = {
	state: {
	loggedIn: false,
	loginError: null,
	username: null
