SYNOPSIS

#include <shishi.h>

int shishi_dk(Shishi * handle, Shishi_key * key, const char * prfconstant, size_t prfconstantlen, Shishi_key * derivedkey);

ARGUMENTS

Shishi * handle

shishi handle as allocated by shishi_init().

Shishi_key * key

input cryptographic key to use.

const char * prfconstant

input array with the constant string.

size_t prfconstantlen

size of input array with the constant string.

Shishi_key * derivedkey

pointer to derived key (allocated by caller).

DERIVE A KEY FROM A KEY AND A CONSTANT THUSLY

DK(KEY, PRFCONSTANT) = SHISHI_RANDOM-TO-KEY(SHISHI_DR(KEY, PRFCONSTANT)).

RETURN VALUE
