Add TLS example under examples/doc-examples (follow-up to PR #831)

[Fatumayattani]

What was wrong?

Issue #700 follow-up. After @guha-rahul’s TLS (PR #831) was merged, there was still no simple runnable example demonstrating how to start a TLS-enabled host in py-libp2p.
Developers needed a small working reference to verify that the new transport layer functions as expected.

How was it fixed?

Added a short example under examples/doc-examples/example_tls.py that demonstrates how to create and start a TLS-secured host using TLSTransport.
The example runs locally, prints the peer ID, and lists the secure multiaddrs for verification.

To-Do

• Add working TLS example under examples/doc-examples
• Coordinate with @yashksaini-coder on AutoTLS work (Issue AutoTLS Support for py-libp2p #555), as guided by @seetadev

Output

TLS host starts successfully with secure addresses and confirms that TLS handshake is active.
A sample terminal output is attached below for reference.

Cute Animal Picture

@yashksaini-coder : Thank you so much to you and @Fatumayattani for your efforts. Appreciate it.

It took me sometime to reach this PR as there were close to 12+ PRs in the review queue. Did re-run the CI/CD pipeline. Waiting for the test results.

Wish if you could collaborate with @Fatumayattani and arrive at a good conclusion on this PR soon.

We need a proper screencast demonstrating the example using TLS along with proper documentation to enable interop testing using TLS. CCing @acul71, who could help you on the transport interop testing front using TLS example.

ping me when is merged, I'll try to integrate in interop-tests

Thank you @seetadev and @acul71 for the feedback and clear guidance 🙏
Really appreciate everyone here for the support.

Here’s the screencast showing the TLS example running successfully

@yashksaini-coder , please feel free to add the documentation part to make it easier to use for interop testing 🙏

Got it, I will add the documentation along with discussion post to map the implementation done

Hi @Fatumayattani thanks for the video. Is that showing a python server ? Is there a client also ?

Hi @acul71, yes that’s the server side. I’ll add a simple client example too to make interop testing smoother 🙌🏽

@yashksaini-coder : Thank you so much for considering our feedback points. Appreciate the efforts.

Re-ran the CI/CD pipeline. Hopefully, all the tests should pass.

CCing @acul71, who could use this example for testing transport interop tests.

@yashksaini-coder : Wish if you could resolve the CI/CD issues.

All issues resolved, failing ci-checks. Requesting an update and further feedback.
