Realistically, it's the one that's gonna be used in apt though. (E.g. the existing HTTPS transport uses curl, which uses OpenSSL)

libcurl has many TLS backends. APT before 1.6 actually uses the GnuTLS one.

APT ≥ 1.6 doesn't use libcurl; it uses GnuTLS directly.

I stand corrected, thx.

Sure, my point was more that if it's a serious concern to use OpenSSL (Personally I don't think it is, as a lot of work has been done in recent years to improve that codebase), that other options are available.
