Description Michael Osipov 2023-06-23 09:41:45 UTC 
When compiling 2.0.x against OpenSSL 3.0.x I guess a busload of warnings from clang that the code used is deprecated:

===========

In some point in time we should go through all of these and replace with new code.
Comment 1 Remy Maucherat 2023-06-23 11:08:27 UTC 
Ouch. I had a look and to be honest I don't know how to rewrite this DH stuff (including, but not limited to, the callback which is not documented as having a replacement). I'm pretty sure some stuff breaks without that feature (= testsuite fails). It's good that it's not removed yet (including in 3.2 dev) !

I would assume that all code which is deprecated is still used?
