HI,
I think I'm right in saying that amlen supports tls 1.3 ( I can see references to it in the transport code). Is that correct? It appears to use openssl - does it rely on openssl4j as well?
Did the old IBM product also support TLS 1.3 or does it all depend on what version of openssl is installed??

thanks !
John.

Amlen uses openssl from the OS - if the version of openssl in the OS supports TLS1.3 (e.g. in RHEL8) then Amlen does too. It does not rely on openssl4j the server is written in C.

The old (out of support) IBM product used to bundle openssl (whereas Amlen gets it from the OS) so some versions of the IBM product did bundle versions that supported TLS1.3.

I'm curious why you keep asking about an old EoL IBM product - if you don't want to explain publicly, feel free to drop me an email or a slack message :)

(Slight correction to my previous post - *some* versions of the IBM product bundled openssl. Early versions (<=2.0) didn't but for 5.x we wanted TLS1.3 support and OSs that had it were relatively new. Now TLS1.3 support is widespread, we've gone back to the OS version (which significantly reduces the number of maintenance releases needed).
