Decrypt WPA traffic in Wireshark
Let’s start with the theory to understand why the process of decrypting WiFi traffic in Wireshark requires some effort and why one cannot simply decrypt any captured WiFi traffic even if there is a password from the Access Point.

When transmitting over WiFi, the traffic is encrypted using PTK (the Pairwise transient key can be translated as a Pair of Transition Key). At the same time, PTK is dynamic, that is, it is created anew for each new connection. Thus, it turns out that WiFi traffic for each connection in the same Access Point is encrypted with different PTK, and even for one Client after reconnection, PTK changes. To calculate PTK, you need data from a four-stage handshake, as well as a password from a WiFi network (in fact, you also need other information, such as the network name (SSID), but obtaining this data is not a problem).
