I am trying to decrypt an IEEe802.11 packets on Wireshark.
Manual showed that adding "wpa-pwd" "mypassword:myssid" will do the work but the thing is ssid contain colons and it doesn't work properly.
For example, password is "12345678" and ssid is "MyAP:12:34:56" then how can I decrypt the packets?
I have tried
12345678:MyAp:12:34:56 but it never worked ...

I'm trying to view the payload of QUIC packets although, with no luck. I can decrypt fine TLS packets using SSLLOGFILE file that generated by the browser and load it to Wireshark, I can see HTTPS and DoH and almost all TLS encrypted packets are decrypted correctly.
With QUIC this isnt the case, I can across this post: https://bugs.chromium.org/p/chromium/issues/detail?id=1101691
And there they said that the problem with SSLKEYLOGFILE exporting keys for quic with chrome has been fixed in chrome 89, so I've downloaded chrome 90 (chrome dev version) but still no luck.
Any Ideas what i'm doing wrong?
I can see QUIC packets, can see the client hello and all of the unencrypted QUIC packets are parsed correctly in wireshark, but still no decryption.
Are you using a sufficiently recent version of WireShark? See https://github.com/quicwg/base-drafts/wiki/Tools for details.
Which QUIC version are you trying to decode?
With Chrome 88.0.4324.192 and Wireshark 3.5.0rc0-788 i can succesfully capture and decrypt a quic draft-29 ("h3-29") session.
everyone. I am working a MQTT connection by using TLSv1.2 with the server.
Before asking the question, I've spend sometime to googling the answer. But all the answers I found are talking about how to decrypt SSL trafic in wireshark. This part is done successfully. My question is , after I successfully decrypted the data by setting the CLIENT RANDOM and MASTER SECRET in a file and set it up in TLS deocoding settings in Wireshark, how to decode the decrypted data?
For all decoded data, Wireshark show as seperated tab named as "Decrypted TLS". Once I click the tab, it only shows the raw data as HEX.
Can I ask Wireshark to further decode the raw data by using known protocol such as MQTT?
I'm new to routers and networking so sorry for the maybe obvious question.
When I access my home router through WIFI from my laptop, the WIFI password is being sent from my computer through the WIFI card to router, followd by a response from the router.
Is it possible to use Wireshark or some other application in order to capture these packets (the packets that contains the actual encrypted password and the router response whether it is the correct password or not)?
Thank you.
Yes, you can do that using Wireshark.
Note that the password is sent by an IEEE802.11 management packet and you need to turn on monitor mode to sniffer it.

I am currently connecting my Arduino Uno with the Wi-Fi shield and everything is going great. Where does the print commands (such as WiFi.localIP() or Serial.print() ) print?
I searched and can't find them. I try to access with my web browser to my IP address, but nothing's working.
Serial.print() will print to the serial interface regardless of whether the Wi-Fi shield is connected or not. This is particularly useful for debugging. These characters WILL NOT go out over the Wi-Fi connection.
To print characters to a connected WiFi client (when using the Arduino as a server), look at the example Wi-Fi Web Server.
Notice how the HTTP response is built up line by line. If you're trying to connect to your Arduino through your web browser, you can follow the format in the example and replace it with the necessary text or HTML you want to see in the browser.
I am running wireshark on my home network to learn some things. My network is wpa and I know the key, is it possible to reconstruct the ethernet packets?
I know that after you connect to wpa there is a negotiation of a new key, I assume this is ssl or something like that where it uses a public private key mechanism so I can't see it but I wanted to make sure. if it isn't a public private key mechanism and I capture the handshake can I see the rest?
If the network was an unencrypted open network would I be able to reconstruct the communications?
Also, I am running wireshark in monitor mode so that I get the raw wifi packets. Do I have to worry about channel or does it catch all wifi over the air.
Thank you
To do that, you would have to implement router's firmware in own software (cipher/decipher routines). Software that could interest you is CommView and aircrack-ng.
Do I have to worry about channel or does it catch all wifi over the
air.
Yes, you do have to set the channel on the adapter to the channel where you expect the traffic.
