shishi_dr3
Api function
Usage
#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_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. |
Overview
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.
