Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) is a security mechanism used to authenticate and validate users on a wireless LAN (WLAN) or Wi-Fi connection. It is a variation of the WPA security protocol. WPA-PSK is also known as WPA2-PSK or WPA Personal.
WPA PSK (Raw Key) Generator
The Wireshark WPA Pre-shared Key Generator provides an easy way to converta WPA passphrase and SSID to the 256-bit pre-shared ('raw') key used for keyderivation.
Directions:
Type or paste in your WPA passphrase and SSID below. Wait awhile. The PSK will be calculated by your browser. Javascriptisn't known for its blistering crypto speed. None of thisinformation will be sent over the network. Run a trace with Wireshark ifyou don't believe us.

I have a lot of traffic...ANSWER: SteelCentral™ AppResponse 11![]()
What good is a fancy new wireless encryption and authentication system (wpa-psk)if you use an easy-to-guess passphrase?
Answer: Not very good. WPA, as part of the initial implementation of 802.11i, includesa host of new features designed to patch the gaping holes in the previous wireless encryption and authentication protocol, WEP. Wpa-psk, the less secure version of WPA for those of us who do not have a PEAP authentication server, relies upon a common pre-shared key ('psk' - get it??) to initialize the communication.
Unfortunately, a clever hacker can trick your wireless basestation into revealingthe initial handshake between your basestation and wireless clients, and then run abrute-force/dictionary attack on the handshake to recover the pre-shared key. Even worse, theattack can be done offline at a high rate of speed.
The upshot: While wpa-psk will keep out casual wardrivers, a determined intruder, givenenough time, can always hack into your network. If you use a poor passphrase (like, oh, 'passphrase'), a dictionary attack could render your wpa-psk useless in 30 seconds. Your goal,then, is to use a sufficiently strong password that would require an intruder to spend years(given today's computing power) to brute-force your passphrase. And, frankly, if you have data thatpeople would spend years trying to obtain, then perhaps you should look elsewhere for somestronger security.

In the meantime, there are websites devoted to telling you how to generate random keys athome, as well as some sites that generate various WEP keys for you. This page will generatea wpa-psk of whatever size you like, safely and securely. (Plus you don't have to roll a diea couple hundred times.)
How does this page work?
This page uses the javascript functions built into your web browser to generate a random password for you. If you want to see the code for yourself, find your browser's'view-source' menu item.
Wpa Psk Vs Wpa Default Password
Importantly, using javascript, all of the computational work for key generation takes place on your own computer. No-one but you knows what random key you got. It is not sent across the internet and there is no way for me (or anyone else) to record your key.
Compare a few other sites on the internet, wherethe actual key generation takes place on their webserver and they transmit the keyto you (hopefully over a secure connection). If you use one of these services, your keyis only as secure as your trust for their webservers.
Note: The code for key generation is based upon that distributed freely by the kindfolks at WarewolfLabs.
