Simple module implementing the hashcash algorithm
$ npm install hashcashgen
var hashcashgen = require'hashcashgen'idgen = require'idgen'assert = require'assert'var challenge = idgen;// to generate a hashcash, call hashcashgen(challenge [, strength] [, callback])// default strength is 3.var hashcash = hashcashgenchallenge 4;// to check the hashcash, call hashcashgen.check(challenge [, strength], hashcash)asserthashcashgencheckchallenge 4 hashcash;
If callback is passed, it will be called with (err, hashcash) as arguments instead of returning a hashcash. Useful to avoid blocking the event loop.
hashcashgen is usable in the browser thanks to browserify!
Universal browser module is packaged in
./browser/hashcashgen.js. Easily servable
by your node server with this method:
var hashcashgen = require'hashcashgen'express = require'express'var app = express;appget'/js/hashcashgen.js' hashcashgenmiddleware;
Then in your HTML:
./test/server for an example.
$ npm install -g hashcashgen$ hashcashgen -s 4 somepigsomepig:30998$ echo -n "somepig:30998" | shasum000007620b1539af6cf6145f368cc406b77ebaae -
