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.
