Implement DTSL (encrypted UDP sockets) #5270
Description
Activity
I don't believe it's implemented. A while back, I took a look at doing so, and despite what I said in that thread, I did indeed abandon it.
IIRC, the underlying stack (mbedtls) supports this.
Any plans to implement DTLS?
Not in the short term, but in the medium term (~3 months) it could be done if there's enough interest.

[-]DTSL example - missing on the docs.[/-][+]Implement DTSL (encrypted UDP sockets)[/+]on Oct 30, 2019 I am also interested in DTLS support, however I would prefer it to be done similarly to ucryptolib.aes with encrypt/decrypt methods. The reason is that the output would be used as UDP payload for NB-IoT modem controlled via AT commands which is not bound to lwip.

Note that the
sslmodule can currently be used stand-alone, ie without lwip/sockets. It just requires a suitable stream (eg user class derived fromio.IOBase) to be passed in tossl.wrap_socketI would envisage a similar thing for DTLS.Reacted by dmartauzAny plans to implement DTLS?

I'm interested as well, I'm searching for an option to encrypt/decrypt UDP packets on an ESP32.
The possibility to communicate securely definitely makes sense, also in the IoT/embedded world :)

Hello.
Are there any example about to use DTLS? I would like to use UDP protocol to communicate, but in the secure mode, like as a TCP socket using TLS. I found on docs just about ussl for TCP sockets.
Thank you.
