Please update the README.md, which says this lib requires Openssl 1.1

Updated, all entries mentioning OpenSSL.

Nice, good for consistency and code clean-up.

I'd like to see some of the (global) Dockerfiles and build instructions updated. I failed to find libssl3, even as PPA, for Debian 11 and Ubuntu 20.

For Ubuntu 20 the only option is manual install (from sources). Will have to see for Debian.

There are still some references to detection of OpenSSL v3, more code which can be reduced:
