Thanks a lot for pushing this through, @acul71 — great work on tracking this down and fixing it cleanly.

Resolving the TLS failure caused by certificate extensions (and aligning with the spec) unblocks an important class of interop tests, and it’s great to see the rust ↔ python TLS mismatch addressed directly. The additional handling around the exception also makes the fix much more robust.

Appreciate the clear context and follow-up references as well — that made review and merge straightforward. This is a solid improvement for Python support in libp2p.

Looking forward to more contributions like this — thanks again for the effort 🙏
