If we have “TK (Temporal Key)” then we can select TK option from drop down and decrypt WPA/WPA2 frames. ♦ How to “TK” from Wireshark decryption windows? Use below link to generate the key.įollow below screenshot to see the steps: To do this we need to generate 256bit PSK. ♦ How to use “WPA-PSK” from Wireshark decryption windows? ♦ Decrypted frame: WPA-TKIP decrypted data frame ♦ WPA-TKIP encrypted frame: WPA-TKIP encrypted data frame ♦ Decrypted frame: WPA2-AES decrypted data frame

♦ WPA2-AES Encrypted frame: WPA2-AES encrypted Data frame Here only WEP key length is more than A, B.

♣ Decrypted frame: WEP-128 decrypted data Open the window showed in step “h” and follow below screenshot for steps. ♦ How to decrypt WEP-128 encrypted frame? ♦ WEP-128 Encrypted frame: WEP-128 encrypted data frame ♦ WEP-SHARED-64 Encrypted frame: WEP-64 Shared encrypted data frameĭecrypted frame: WEP-64 Shared decrypted data frame On Wireshark version ex: 3.4.2, there is a direct option to open step “h”. ♦ Frame after decryption: WEP-64 decrypted data frame Let’s follow the screenshots to understand the steps ♦ WEP-OPEN-64 Encrypted frame screenshot: WEP-64 encrypted Data Here is the screenshot for no security data frame. If no security is configured in AP then the communication between client and AP is visible in Wireshark. Now we have understood the differences between encrypted and decrypted packet, let’s see the steps to decrypt wireless frame with different security. In this frame we get idea of what is the actual data (Here ICMP) instead of just QoS Data. īelow is the decrypted frame or no security is configured. ♦b♦ Frame is decrypted or None/Open security. If we are able to decrypt this frame then we can see the actual data. This means, all those layers are encoded inside wireless data. ♦ There is no other layers are visible in frame details. ♦ Wireless data frame shows as Data or QoS Data

There are two places where we should look into to understand an encrypted frame. Here we will try to decrypt all types of wireless security using Wireshark tool.īefore we get into steps of wireless packet decryption, we should know how the data packet looks like ifįrom below screenshot we can see encrypted wireless data frame. ♣ There are different types of security in WLAN.
