#include <shishi.h>

int shishi_dr(Shishi * handle, Shishi_key * key, const char * prfconstant, size_t prfconstantlen, char * derivedrandom, size_t derivedrandomlen);

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.

Derive "random" data from a key and a constant thusly: DR(KEY, PRFCONSTANT) = TRUNCATE(DERIVEDRANDOMLEN, SHISHI_ENCRYPT(KEY, PRFCONSTANT)).

Returns SHISHI_OK iff successful.
