Choose the ssl module or the tls module

What are the differences between the ssl module and the tls module? Which one should I choose to use? thanks！

In MicroPython ssl is a wrapper for tls. All handshakes are TLS.

You should use the ssl module in MicroPython because all standard libraries and examples refer to it by that name, even though it implements TLS protocols.

Of course, you can use tls directly if you want and know what you're doing.

Please take a look at https://github.com/shariltumin/ssl-tls-examples-micropython

TLS is the direct successor to SSL, and all versions of SSL are now obsolete. However, it is common for the term SSL to describe a TLS connection. In most cases, the terms SSL and SSL/TLS refer to the TLS protocol and TLS certificates.

Just use the ssl module, to stay compatible with CPython. There are still differences between CPython's ssl and Micropython's ssl.
