OpenSSL Encrypted RSA pem fails on encryption and decryption. Incompatible with CRuby.

Loading and creating RSA keys from JRuby OpenSSL fails on encrypted RSA pem with password. Works in CRuby.

Examples:

1. 1. Saving Encrypted PEM
      pkeys = OpenSSL::PKey::RSA.generate(1024)
      cipher = OpenSSL::Cipher::Cipher.new('aes-256-cbc')
      pem = pkeys.to_pem(cipher, 'secretpassword') # Fails with OpenSSL::PKey::RSAError: unknown algorithm `aes/cbc/PKCS5Padding' in write_DSAPrivateKey

1. 1. Reading Encrypted PEM
   2. pemstring loaded from previously created file)
      OpenSSL::Pkey::RSA.new(pemstring, 'secretpassword') # Fails with not pub/priv key error. Works in CRuby.
