+Generate a 1024 bit RSA key, and then create a self-signed X.509v3
+certificate with that key. If the do_CA variable is set to true, then
+it will be marked for CA use, otherwise it will get extensions
+appropriate for use with a client certificate. The private key is
+stored as an encrypted PKCS #8 object in another file.
