Lutz
thanks . Your guess is right. I tried with error option and I got this
printed.
"RSA key error: PRNG not seeded"
This is my simple code. could not find out documentation on how to seed
PRNG.
Here is my test program.
==================
int genarateKeys()
{
RSA *rsa, *pub_rsa,*priv_rsa;
unsigned char md[MD5_DIGEST_LENGTH];
unsigned char buffer[1024], *rsaret;
ERR_load_crypto_strings();
CRYPTO_malloc_init();
rsa = RSA_generate_key(512, RSA_F4, callback, NULL);
....
...
}
==================
I could see that , rsa is returning null.
Can you please tell me where and how I can see PRNG.
Thanks

OpenSSL records errors it finds in its error queue. Please use the
ERR_get_error() family of functions to get an indication about
what was wrong.
Best regards,
Lutz
PS. If I should give a guess, without digging deeper into it, all
key-generation routines require random numbers. Did you seed the
PRNG?
