+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+   $ npm install base64id
+
+## Usage
+
+   var base64id = require('base64id');
+
+   var id = base64id.generateId();
