Random number generation always depends on the PRNG
being seeded first.
The man page clearly mentions that.
Add RAND_seed() or RAND_add() with the required
entropy required before calling RAND_bytes(). In a
pseudorandom number generator the seed uniquely
determines the random sequence. So you
This worked..Thanks a million. :-)

If you are looking for a software based solution the OpenSSL PRNG library is
good. There any many interesting software solutions for gathering seed for
the PRNG as well, egd.pl will use a plethora of system information (on unix)
to provide seed.
However hardware based entropy solutions are a bett

If your under Unix, why not use /dev/random or /dev/urandom

you can read as much as is available, with a non-blocking
file descriptor or with FIONREAD. If
Hi,
since I have the same problem and since there is almost no useful
documentation available, what I'm supposed to do if there is
/dev/random but it blocks? Note: Don't have /dev/urandom.
Btw, is there any useful documentation around or in progress?

OpenSSL contains a PRNG that just needs a few random numbers to get it
started. If you're not familiar with what a cryptographically-secure random
number generator is, why they're necesary, or how to seed them, I suggest
you get someone who is familiar with cryptography to do your crypto
