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 derivedran-
       domlen);

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.
