You can use egads that is free and you can download it from http://www.securesw.com/egads/
An example of seeding the PRNG of OpenSSL with EGADS is the following:
int seed_prng(int bytes)
{
int errors;
char *buf;
prngctx_t ctx; egads_init(&ctx, NULL, NULL, &error);
if(error)
return 0; buf = (char*)malloc(bytes);
egads_entropy(&ctx, buf, bytes, &error);
if(!error)
RAND_seed(buf, bytes);
free(buf);egads_destroy(&ctx); return(!error); }
}

Hello All,
I am new to OpenSSL programming and needed some advice. Could someone tell
me, what is the usual way of seeding the PRNG in OpenSSL. I am developing my
server application for Windows platform. Hence I wanted to know the general
practice which everyone is following for Windows since there are no
"/dev/*random" devices. Also since I'm developing a server application,
hence I thought that the "RAND_screen" function also might not be too
helpful.
Thanks in advance,
Ajay.
