shishi handle as allocated by shishi_init().
Shishi_key * key
key to compute checksum with.
int keyusage
integer specifying what this key is used for.
int cksumtype
the checksum algorithm to use.
const char * in
input array with data to integrity protect.
size_t inlen
size of input array with data to integrity protect.
char ** out output array with newly allocated integrity protected data.
size_t * outlen
output variable with length of output array with checksum.
