Hello:
Thanks for your help, but I don´t know what buffer and num I must use.
How I can generate this buffer of random data?. And, num is the entropy,
but, what is it?. How I obtain this entropy?.
I use Windows.
Thanks. Ragards.

Just use FreeBSD 5.X as your operating system, the random device
on it has been completely rewritten to be self-seeding with
high quality random numbers. It harvests from a number of interrupts and
if you don't turn those on it uses the Yarrow PRNG code. And it
also uses the hardware random

Buffer is a memory pointer. Usually something you allocated (in C by
calling malloc) and filled with Data. If you don't know how to do that

Hi All
I was trying to reduce the size of the openSsl library due to memory
constraints on our platform.
I tried to remove three patented ciphers idea, rc5 and mdc2. Any ideas what
more can be done to
reduce the final size of the library?.
thanks and regards

Use /dev/urandom to seed your own PRNG. Or use it to seed OpenSSL's
PRNG.
Why are you asking on this list anyway?
Generating one or two random numbers over a period of time isn't a big
deal. Generating 100,000+ 128 bit random numbers an hour taxes

Hi all,
Due to a number of last minute reports, the final release of OpenSSL
0.9.8 is delayed a few days to give the affected people a chance to
test that the corrections done do fix things as expeted.
So please, if you have sent in a report about something failing with
one of the 0.9.8 betas,
I see things for adding entropy, loading files, etc. I don't see
anything about generating random numbers. Am I missing something so
obvious if it was a snake it would have bitten me by now?

This is a few years old, but may be useful. The code illustrates the
use of the HMAC variant on ANSI X9.17 key generation as described in the
paper, used to generate random byte strings. It uses the hash functions
in the OpenSSL libraries.

Hey OpenSSL guru guys!
Just downloaded http://www.openssl.org/source/openssl-0.9.7g.tar.gz
ALL the header files in openssl-0.9.7g\include\openssl are zero bytes in
length!??
Is there something wrong with the distribution or am I doing something
stupid?
Thanks in advance,
Pj.
