Generate a X509 Certificate for testing purposes

Small script to generate a X509 certificate for testing purposes. In my case, for generating signed PDF documents. This will write the certificate and it's key out into a Pkcs 12 store. It relies on the BouncyCastle library (version 1.7 worked fine).
