As the title specifies, I'm trying to understand the minimum requirements for a utility like Wireshark to decrypt the packets from another device on a simple home network using WPA2 personal (AES).
Lets say packets between Device B and the router are captured on Device A through Wireshark's monitor mode. Just making sure, but does Device A have to be already connected to the network to capture these packets? (I believe the answer is no?)
As far as my searching and understanding, at minimum you need to have the preshared key/wireless password as well as have captured the EAPOL packets between the router and Device B to decrypt the packets from the scenario above. Is this correct, or is more/less needed?
