A small shell script to generate a private key, a self signed certificate using OpenSSL and finally importing them into a Java keystore. A self signed certificate is usually used during development and test phases, so to make your life easier, the key created is not protected by password. The .p12 file being created by openssl is password protected because lot of users reported that otherwise keytool would refuse to import it. The self signed certificate will expire after 9999 days, I hope it is enough time to complete your development.
