It would be very useful a Desktop solution to be able to communicate as a client and or sever.
Adding an option for selecting TLS1.2 or TLS1.3.
A second option where it could be possible to add the certificates.
An option similar to the actual one for being able to select the IP address and Port to communicate

And a place to add the packet to send as the ASCII or HEX box..

Thanks for opening this issue.

This screenshot looks like you are using Windows. Packet Sender for Windows uses OpenSSL which can send TLSv1.3. You can go to Help --> About, and then you can see the OpenSSL (or native SSL for other installations) library in use.

The currently shipping one inside Packet Sender is v3.0.7, which does support TLSv1.3. If you are looking for specific cipher suites, you can browse the changelog here: https://www.openssl.org/news/changelog.txt

If you want to manipulate the certificates used by Packet Sender server, cert.pem and key.pem can be found at %LOCALAPPDATA%\PacketSender\
