functions. Use for public key encryption jobs.

*
* // To configure
* // 1. Set OPEN_SSL_CONF_PATH to the path of your
openssl.cnf file.
* // 2. Set OPEN_SSL_PASSPHRASE to any passphrase.
* // 3. Use the OpenSSL::do_csr method to generate your
private and public keys (see next section).
* // 4. Save the private key somewhere offline and save
your public key somewhere on this machine.
* // 5. Set OPEN_SSL_PUBKEY_PATH to the public key's path.

* // To generate keys
