Key = PBKDF2(passphrase, ssid, 4096, 256) The function PBKDF2 is a standardized method to derive a key from a passphrase. It is specified in RFC2898 with a clear explanation on how to compute it. The function needs an underlying pseudorandom function. In the case of WPA, the underlying function is HMAC-SHA1. SG WLAN Key Generator. About the WLAN Key Generator. The SG WLAN Key Generator is a tool that allows for quick, valid, and strong WEP/WPA key generation. It uses the 94 standard ASCII characters (with codes 32 to 126) for maximum compatability. The WEP/WPA Key Generator supports 64bit, 128bit, 152bit & 256bit WEP keys, and 160bit, 504bit WPA/WPA2 keys for maximum security. Alternatively, if you require to generate a key based on a custom passphrase (most cases), you can use the Custom WEP/WPA Key Generator.
What Is A Wpa2 Psk PassphraseWhat 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. Halo combat evolved download link. 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.) Windows xp product key generator download.
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.
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.
