• cryptoSecretStreamPush

   abstract boolean cryptoSecretStreamPush(SecretStream.State state, Array<byte> cipher, Array<byte> message, int messageLen, byte tag)

  Encrypt a {@code message}. This is like cryptoSecretStreamPushbut without additional data or an address to store the cipher.

  Parameters:
