  3. \brief This function encrypts or decrypts a message of any size, storing
  4. the result in output. It requires that the Rabbit ctx structure be
  5. initialized with a key and an iv before encryption.
  6. \return 0 Returned on successfully encrypting/decrypting input
  7. \return BAD_ALIGN_E Returned if the input message is not 4-byte aligned
  8. but is required to be by XSTREAM_ALIGN, but NO_WOLFSSL_ALLOC_ALIGN is
  9. defined
  10. \return MEMORY_E Returned if there is an error allocating memory to
  11. align the message, if NO_WOLFSSL_ALLOC_ALIGN is not defined
  12. \param ctx pointer to the Rabbit structure to use for encryption/decryption
  13. \param output pointer to the buffer in which to store the processed
  14. message. Should be at least msglen long
  15. \param input pointer to the buffer containing the message to process
  16. \param msglen the length of the message to process
