No compatibility with OpenSSL 3?

[h4rp00n33r]

Hey folks,

I tried to run AirConnect on my Debian 12 server. Debian 12 comes with OpenSSL 3 and libssl1.1 is not in the repositories anymore. So I could add libssl1.1 manually (#522) but I'm a little bit concerned about security aspects (running an outdated libssl version without support).

So I have two questions:

1. Is there no chance to get AirConnect running with libssl3?
2. Which libssl-Version is included in the static-version?

Thanks and greetings from Germany.

I'll have to have a look at OpenSSL 3 and how to get compatibility. I think I've compiled the static version against 1.1.x

Okay thanks a lot. Do you want me to keep this issue open in order to track it?

Yes please

For any Debian/Ubuntu users

I was able to compile this dynamically by installing libssl-dev and linking with -lssl -lcrypto. To compile it statically, I also had to install libzstd-dev and zlib1g-dev, and linked with -lssl -lcrypto -lzstd -lz -static-libgcc. Unfortunately, I don't know how portable this is because I get the following warnings related to the crypto library:
