shishi_aes_cts - API function

       Shishi * handle
                   shishi handle as allocated by shishi_init().

       int decryptp
                   0 to indicate encryption, non-0 to indicate decryption.

       const char * key
                   input character array with key to use.

       size_t keylen
                   length of input character array with key to use.

       const char iv[16]
                   input character array with initialization vector to use, or NULL.

       char * ivout[16]
                   output character array with updated initialization vector, or NULL.

       const char * in
                   input character array of data to encrypt/decrypt.

       size_t inlen
                   length of input character array of data to encrypt/decrypt.

       char ** out newly allocated character array with encrypted/decrypted data.

       Encrypt or decrypt data (depending on decryptp) using AES in  CBC-CTS  mode.   The  length  of  the  key,
       keylen, decide if AES 128 or AES 256 should be used.  The out buffer must be deallocated by the caller.
