Node.js module that generates a cryptographically secure random string with a given length

var srs = require('secure-random-string');

This may include alphanumeric characters as well as the following characters: +, /, =.

// Sync
var result = srs();

// Async
srs(function(err, sr) {
	console.log(sr);
});

Optionally, you can specify a 'length' option to specify a length.

// sync
var result = srs({length: 256});

// async
srs({length: 256}, function(err, sr) {
	console.log(sr);
});

Optionally, you can specify a 'alphanumeric' option to get a alphanumerical chars only.

// sync
var result = srs({alphanumeric: true});

// async
srs({alphanumeric: true}, function(err, sr) {
	console.log(sr);
});

An error is possible if there is not enough accumulated entropy to generate cryptographically strong data. In other words, this will not block even if all entropy sources are drained. Note that the sync API throws an exception, while the async API returns the error to the callback.
