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.
