TLS documentation

[seetadev]

The documentation plan should focus directly on:

• Explaining what TLS support means in the context of py-libp2p.
• How to enable, configure, and test TLS in a py-libp2p setup.
• The interop expectations with other libp2p implementations.

Here’s a TLS-specific documentation outline you can start with:

Py-libp2p – TLS Support Documentation (for Issue #700)

1. Overview of TLS in Libp2p (High Priority)

• Purpose of TLS in P2P networking
• How it fits into libp2p’s connection security modules
• Current status of TLS in py-libp2p vs other implementations

2. Installation Requirements (Medium Priority)

• Any extra Python dependencies for TLS (e.g., cryptography, pyOpenSSL)
• Supported Python versions and platforms
• OpenSSL compatibility notes

3. Enabling TLS in py-libp2p (High Priority)

• Example:

  from libp2p import new_node
  from libp2p.security.tls.transport import TLSTransport
  
  async def main():
      node = await new_node(security_transports=[TLSTransport()])
      await node.listen("/ip4/0.0.0.0/tcp/8000")
      print("TLS-enabled node listening...")
  
  if __name__ == "__main__":
      import asyncio
      asyncio.run(main())

• Configuration options (certificates, key management)

• Default behavior if no config is provided

4. Certificate Management (Medium Priority)

• Self-signed vs CA-signed
• Generating certificates for local development
• Secure storage and rotation

5. Testing TLS Connections (High Priority)

• Local loopback TLS test between two Python peers
• Interop test with go-libp2p or js-libp2p TLS nodes
• Debugging handshake failures

6. Security Considerations (Medium Priority)

• Common TLS misconfigurations
• How py-libp2p handles peer identity validation
• Future roadmap for TLS features

7. Troubleshooting (Medium Priority)

• Certificate not trusted errors
• Protocol negotiation issues
• Logs and debug output
