 Generate an RSA Keypair:
 
 ```javascript
-var PromiseA = require('bluebird');
-var RSA = PromiseA.promisify(require('rsa-compat').RSA);
+var RSA = require('rsa-compat').RSA;
 
 var bitlen = 1024;
 var exp = 65537;
 var options = { public: true, pem: true, internal: true };
 
-RSA.generateKeypair(bitlen, exp, options).then(function (keypair) {
+RSA.generateKeypair(bitlen, exp, options, function (err, keypair) {
   console.log(keypair);
 });
 ```

 `console.log(keypair)`:
