uninitialized constant Sandal::Enc::AGCM::SecureRandom

Following your example, and generating the keys as you specified, I get this error:

alg = Sandal::Enc::Alg::RSA_OAEP.new(File.read('rsa_public_key.pem'))
encrypter = Sandal::Enc::A128GCM.new(alg)

jwe_token = Sandal.encrypt_token(jws_token, encrypter, {
  'kid': 'your rsa key',
  'cty': 'JWT'
})
NameError: uninitialized constant Sandal::Enc::AGCM::SecureRandom

@gregbeech any idea what's wrong?
