What are WEP WPA keys?

What are WEP WPA keys?

WPA (Wi-Fi Protected Access) is a wireless security protocol released in 2003 to address the growing vulnerabilities of its predecessor, WEP. The WPA Wi-Fi protocol is more secure than WEP, because it uses a 256-bit key for encryption, which is a major upgrade from the 64-bit and 128-bit keys used by the WEP system.

How is WEP key generated?

Standard 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the RC4 key. At the time that the original WEP standard was drafted, the U.S. Government’s export restrictions on cryptographic technology limited the key size.

How do I find my WPA PSK WPA2 PSK key?

Where do I find my WEP key or WPA/WPA2 preshared key/passphrase?

  1. Contact your system support person. The person who set up your network usually keeps the WEP key or WPA/WPA2 preshared key/passphrase.
  2. See the documentation that came with your access point (wireless router).
  3. View the security settings on the access point.

What is Eapol handshake?

EAPOL stands for Extensible Authentication Protocol(EAP) over LAN. A simple 4-way handshake is shown pictorially below. A top level description of a successful 4-Way-Handshake is explained below. At the start of the 4-way handshake, both the Access Point and the 802.11 station contain the PMK.

How do you decode packets in Wireshark?


  1. On the Wireshark packet list, right mouse click on one of UDP packet.
  2. Select Decode As menu.
  3. On the Decode As window, select Transport menu on the top.
  4. Select Both on the middle of UDP port(s) as section.
  5. On the right protocol list, select RTP in order to the selected session to be decoded as RTP.

How do I know if my Wi-Fi is WEP or WPA?

How to Check Your Wi-Fi Security Type in Android. To check on an Android phone, go into Settings, then open the Wi-Fi category. Select the router you’re connected to and view its details. It will state what security type your connection is.

How do I decode in Wireshark?

What is a WEP number?

Wired Equivalent Privacy (WEP) is either a 64-bit key with 10 hexadecimal digits or a 128-bit WEP key with 26 hexadecimal digits. This will prevent other users from connecting to your wireless network. It will also protect your wireless transmissions/communications from being accessed or received by other users.

What is PMK in WiFi?

Described in the 802.11i standard (section 8.4. 1.2. 1), there exists a methodology by which clients undergoing an 802.1X authentication process can skip the EAP exchange whilst roaming between APs. This technique is known as PMK (Pairwise Master Key) caching.

Can Wireshark decode encrypted packets?

I mentioned in my Tcpdump Masterclass that Wireshark is capable of decrypting SSL/TLS encrypted data in packets captured in any supported format and that if anyone wanted to know how for them to ask.

What is the WEP/WPA keys window?

The WEP/WPA Keys window allows WEP, WPA, or WPA2 keys to be entered for the decryption of captured packets. Without these keys, the program will not be able to decrypt data packets being transmitted on your WLAN.

How to generate a random WEP/WPA key?

You can use the Random WEP/WPA Key Generatorto generate a random WEP or WPA key. Simply choose the desired key length using the drop-down menu, and one will be generated for you. The WEP/WPA Key Generator supports 64bit, 128bit, 152bit & 256bit WEP keys, and 160bit, 504bit WPA/WPA2 keys for maximum security.

Can I use WEP and WPA passphrases simultaneously?

Since some WLANs use mixed mode encryption, where both WEP- and WPA-enabled clients can authenticate, you can use a WEP key and WPA passphrase simultaneously. The standard allows you to use up to four WEP keys, so you can specify one, two, three, or four keys. The key length drop-down list allows you to select the key length.

How do I decrypt WPA or WPA2 in PSK mode?

CommView for WiFi supports decryption of WPA or WPA2 in Pre-Shared Key (PSK) mode using Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard/Counter CBC-MAC Protocol (AES/CCMP) data encryption. You can enter either a passphrase or a hexadecimal key that is 64 characters long.
