# fast-srp

Is a pure [NodeJS](https://nodejs.org/) implementation of the [SRP6a protocol](http://srp.stanford.edu/).

It's a derived work of [Jed Parson](http://jedparsons.com/)'s [node-srp](https://github.com/jedp/node-srp) and [Tom Wu](http://www-cs-students.stanford.edu/~tjw/)'s [jsbn](http://www-cs-students.stanford.edu/~tjw/jsbn/).

## Creating the Verifier

```javascript

'use strict';

var srp6a = require('fast-srp');

/**

 * Computes the verifier of a user. Only needed to add the user to the auth system.

 *

 * I: (string)		Username to compute verifier

 * P: (string)		Password

 * callback: (function) Callback function with two params; error, verifier

 *

 * returns: verifier (Buffer)

 *

 */

var srp6a_create_user = function(I, P, callback) {

  srp6a.genKey(32, function(error, salt) {

	  if(error) {

	    callback(error);

	  }

	  var v = srp6a.computeVerifier(srp6a.params[4096], salt, new Buffer(I), new Buffer(P));

	  callback(null, v);

  });

}

srp6a_create_user('Zarmack Tanen', '*****', function(error, verifier) {

  if(error)

    throw error;

  console.log("SRP6a verifier of Zarmack Tanen user is " + verifier.toString('hex'));

});

```
