SYNOPSIS

       #include <shishi.h>

ARGUMENTS

       Shishi_crypto * ctx
                   crypto context as returned by shishi_crypto().

       const char * in

       size_t inlen
                   size of input array with data to decrypt.

       char ** out output array with newly allocated decrypted data.

       size_t * outlen
