eap-tls rekey sample with CCMP
Build Information:
Paste the COMPLETE build information from "Help->About Wireshark", "wireshark
-v", or "tshark -v".
--
Wireshark is not able to decrypt packages after an WPA-rekey.
Proposed fix https://code.wireshark.org/review/#/c/8268/
The attached files can be used to test the patch.
You have to configure the following PSKs in wireshark to be able to fully
decode the EAP-TLS samples.
In these captures the Pairwaise Key was rekeyed every 120s and the group key
every 60s (very unusual, showcase only settings.):

Rekeys are also possible with WPA-PSK. Also one example for that:
