Hello.
I'll collect entropy(random bytes) myself on Windows. How many random
bytes I must give for function RAND_seed to seed PRNG properly in two cases:
1) Generating RSA keys.
2) Programming SSL-TLS. And where I must call RAND_seed during SSL-TLS
programming?
I think int
Ok, thanks a lot :)

Hello Mailinglist,
in the OpenSSL documentation is written that I should initialize with
RAND_seed() before using RSA_public_encrypt() and RSA_generate_key_ex(). But I
havent found any good examples that show how to do this. (For Windows)
I found this example in the test folder over and over

I hope I'm correct in my statements. I'm also a relative newbie to OpenSSL.

If it is, it is failing because I'm getting failure to seed the PRNG errors
on my test systems that don't have /dev/

I have
essentially the same question. I need to be able to call RAND_seed() on both
Windows and UNIX.

Ok I don't know if I understood your problem correctly, but if you're looking for ways for seeding you can always use current system time, I believe this is pretty much available on all systems.

Change ST(1) in SSLeay.xs:2142 to ST(0), this is presumably the id of the

Hi all
I've run into a problem with Net::SSLeay::RAND_seed($buf).
I'm working on WinNT4 with Net::SSLeay 1.05 and OpenSSL 0.9.5.
(I'll be posting instructions how to get those two to work together on NT as
soon as the Net::SSLeay homepage is up again)
