OpenSSL versions software vendors are using

Daniel Nashed  5 December 2021 10:02:08

When looking into Splunk over the weekend I realized again that software vendors often are using quite old versions of important security related software like OpenSSL.
So I looked into the OpenSSL history and found out that OpenSSL 1.0.2 was the last version which was FIPS 140 supported.

After removal of FIPS 140 support in 1.1.0 it is back in OpenSSL 3.0.

So this hopefully open the door for many software vendors to switch to a newer OpenSSL version.
My current Splunk server on Docker uses: "OpenSSL 1.0.2y-fips  16 Feb 2021".

This is quite up to date from security patch point of view.
But when you have a look into the major improvements in more recent OpenSSL versions, it is really time to move.

I have already build my nshcertool on OpenSSL 3.0 and there have been only some minor changes I had to take care of.
It now compiles and works for both versions.  

Notes/Domino is currently using OpenSSL 1.1.1 and now that OpenSSL 3.0 is available switching to OpenSSL 3.0 is the next logical move.

Redhat switched to OpenSSL 3.0 with RHEL/Centos Stream 9 as I mentioned in an earlier post.
So this might be another reason why software vendors might look into OpenSSL 3.0 soon.

On the other hand relying on the OpenSSL version installed on an operating system might not be the best strategy in most cases.
But shipping your own OpenSSL version requires to build it in a way that it can run on the oldest OS version you support.

Nice one. I am setting up a proxmox-server upcomming week. waiting for the psu and another memory stick to arrive.then I will have a big learning curve to climb :-) but thats the fun isnt it ?
