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

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.
