node-srp uses [bignum](https://github.com/justmoon/node-bignum) to handle the big numbers, but I've got many problems with that library mainly compiling it in Windows 7. Finally I've ported the node-srp to use [jsbn](http://www-cs-students.stanford.edu/~tjw/jsbn/). node-srp uses [bignum](https://github.com/justmoon/node-bignum) to handle the big numbers, but I've got many problems with that library mainly compiling it in Windows 7.

## Creating the Verifier
```javascript
'use strict';
var srp6a = require('fast-srp');
//
// I:
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'));
});
```
