I've sent 3 e-mails to the list over the past 10 days, but not a single
reply. I'm a bit worried, as I don't know how else to get help on OpenSSL.
I'm using Openssl to talk to a server that expects to re-use ssl sessions
when a client needs to open many SSL connections. I have the same code
work
You use the command line utility of your own machine, or another, to test
SSL functionality:
Here is the way you connect to google:
openssl s_client -connect www.google.com:443 -debug
Here are some more examples:

Well there is a limit on key sizes for public key algorithms to avoid their
use as a DoS attack. This limit is currently 661 bits for

Hello guyz and cryptobrains! :P
One of the main disadvantages of EC on openssl seems to be the inability
to create arbitrary-sized keys and advantage for RSA: you can create 32768
bit RSA key but... not greater than 521 bits on ECC.
Will this continue to be a disadvantage or can 32768 RSA key be

Hello,
To generate EC key pair you should:
- choose EC curve (eg secp256r1, secp384r1, ...)
- generate private key: d = random(0,...,n) (0 < d < n)
- generate public key dG = d*G
where n = generator order, G = generator.
If you have private key d then you should calculate public key dG =

Hi,
I have successfully built x64 version of FIPS object module (1.2.3) and
openSSL 0.9.8.u on Windows 7 with Visual Studio 2010. However,
out32dll/fips_test_suite.exe fails with following error.
