Usage
#include <shishi.h>
int shishi_dk(Shishi * handle, Shishi_key * key, const char * prfconstant, size_t prfconstantlen, Shishi_key * derivedkey);
Arguments

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)).
