I am referring this post https://www.openssl.org/blog/blog/2015/05/20/logjam-freak-upcoming-changes/ and trying to see a website is vulnerable to Logjam or not.
I try with www.google.com:443 but I am getting Server Temp Key: X25519, 253 bits. Does this mean Google is vulnerable to LogJam?
(The command to use is
$ openssl s_client -connect www.example.com:443 -cipher "EDH")
I would like to try this in my SIT IP and port, which is not open to public, so I am not sure the way I do is correct or not.
As my understanding, Google will not likely be vulnerable to Logjam, right?
If you have a better way to verify, kindly advise.
