Hi, we have linked FIPS compliant openssl version against our applications.
Now few applications are using libc rand function. For FIPS compliance, applications have to call approved SP 800-90A DRBG implementation. I was planning to replace libc rand with RAND_bytes for the same. But rand() returns max value of 32767 . Is there a recomended way to convert RAND_bytes to libc rand() something like this? unsigned char buf[2]; RAND_bytes(buf,2) int *rndp = malloc(4); memcpy(rndp,buf,2); return (unsigned) ((*rndp) % 32768) Please suggest . Is there a way to give number of bits instead of bytes to RAND_bytes? Regards,
