I have found a document which explained how to decrypt WPA2 enterprise, but I couldn't reproduce it in my PC.

I have downloaded the capture from the link which the document showed,

and used the PMK in the document. Tried 'wpa-psk' and 'wpa-pwd', both of them were not working.

But it shown as invalid key format.

My Wireshark version is

Version 2.4.6 (v2.4.6-0-ge2f395aa12)

Seems to work fine on all versions I have tested - decrypts up to the first rekey as I only tested the first PMK. When I paste the PMK into the field for wpa-psk (in this case, as we only have the PMK, NOT a passphrase/SSID), it says invalid but when I press enter or leave the dialog box and come back, this notice is cleared. Wireshark 2.6.1 is current; I doubt it matters, but if you did stumble across a defect, they would only fix in the latest version anyway so you might as well be using that if you can. Tested in Linux/2.4.6 and Windows/2.6.1.

Thanks, I have found what my issue is. I input 3 Keys in the same line.

Actually, they are 3 PMK keys.
