tool like openssl for windows

Hi experts,

I am a network engineer and don't normally deal with coding or IT forensics.
What I am looking to do is see the type of response from our SSL sites when it receives an SSLV2 requests.
I've read that openssl does the trick but I don't think it installs on Windows (correct me if I am wrong). What other tools are available for this?

I haven't used this or know anyone who has, but it looks like This app from Shining Light might do the trick.

Why not just fire up a Unix-based VM? Ubuntu is nice and friendly to those who are used to Windows, then you can just use "openssl s_client" combined with whatever special options you need for your testing. This approach realistically shouldn't take long at all these days, it's a pretty common practice.

Windows binaries for openssl:

Hope this helps.

Thank you. i was able to load openssl on my Windows 64-bit computer.
I went into DOS and typed in c:\openssl-win64\bin\openssl

Now I get an OPENSSL prompt.

I will diable sslv3 and only allow sslv2 on my browser. I want to then go to www.chase.com and see how it responds.
Can someone provide a same syntax for accomplishing this? Chase IP is 159.53.60.115

I don't see a syntax for S-client.

OpenSSL> s-client ?
openssl:Error: 's-client' is an invalid command.

OpenSSL> openssl s_client ?
openssl:Error: 'openssl' is an invalid command.

s_client is an argument to give after 'openssl' on the command line, not in interactive mode (although you may be able to, but for the sake of this thread just use the following command).

openssl s_client -connect hostname:port -ssl2

Open in new window

Run that and if you see the certificate, you *should* be good.

I should have clarified. If you see the certificate, then SSLv2 is enabled. Not sure what you are trying to accomplish, but disabling SSLv2 and weak ciphers are good things to do.

Papertrip, thank you.
I was looking to verify that ssl2 was turned off on my site. Since I didn't see the cert when I ran that command I assume it is turned off.
