Re-Enable TLS 1.0 for OpenSSL-based Clients on Debian Buster
8. März 2020 in GNU/Linux.
OpenSSL shipped with Debian 10 „Buster“ disables TLS protocol versions below 1.2. The web-browsers Chromium and Firefox ship with an embedded SSL implementation and are not affected (they will issue warnings about legacy websites), but it can cause problems with curl, Squid and other clients that are linked against the OpenSSL.

Die Browser-Entwicklerwerkzeuge sind nett, aber der Netzwerktraffic-Reiter hat (insbesondere bei FF) ein Problem, er reisst die Performance so weit runter, dass einem das Gesicht einschläft. Auf macOS verwende ich „mitmproxy“, um HTTP und HTTPS zwischen Browser und Server zu protokollieren. Das Verfahren erfordert die Installation von „homebrew“ (ein Paket-Manager für macOS) und damit dann „mitmproxy“ […]
