NAME
shishi_dr - API function
SYNOPSIS
#include <shishi.h>
int shishi_dr(Shishi * handle, Shishi_key * key, const char *
prfconstant, size_t prfconstantlen, char * derivedrandom, size_t
derivedrandomlen);
ARGUMENTS
Shishi * handle
shishi handle as allocated by shishi_init().
Shishi_key * key
input array with cryptographic key to use.
const char * prfconstant
input array with the constant string.
size_t prfconstantlen
size of input array with the constant string.
char * derivedrandom
output array with derived random data.
size_t derivedrandomlen
size of output array with derived random data.
DESCRIPTION
Derive "random" data from a key and a constant thusly: DR(KEY,
PRFCONSTANT) = TRUNCATE(DERIVEDRANDOMLEN, SHISHI_ENCRYPT(KEY,
PRFCONSTANT)).
RETURN VALUE
Returns SHISHI_OK iff successful.
