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