The person who set up your network usually keeps the WEP key or WPA/WPA2 preshared key/passphrase. If your wireless network was set up by your Internet Service Provider (ISP), then you might find the information in the documentation they provided. See the documentation that came with your access point (wireless router).
- Select the size of the key you would like to generate. I've preselected the best size for you.
- Hit the 'generate' button. Your random key will appear in the text box.
- Select the random key (click on the box and type [cntrl-a]) and copy it to yourclipboard [cntrl-c]. Be sure you select the entire key!
- Paste [cntrl-v] this key into the configuration screens for both your wireless basestationand your wireless client.

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.
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.

Generate Wpa Pre-shared Key
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used.[1]
Key[edit]
To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms. The term PSK is used in Wi-Fi encryption such as Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), where the method is called WPA-PSK or WPA2-PSK, and also in the Extensible Authentication Protocol (EAP), where it is known as EAP-PSK. In all these cases, both the wireless access points (AP) and all clients share the same key.[2]
The characteristics of this secret or key are determined by the system which uses it; some system designs require that such keys be in a particular format. It can be a password, a passphrase, or a hexadecimal string. The secret is used by all systems involved in the cryptographic processes used to secure the traffic between the systems.
Crypto systems rely on one or more keys for confidentiality. One particular attack is always possible against keys, the brute force key space search attack. A sufficiently long, randomly chosen, key can resist any practical brute force attack, though not in principle if an attacker has sufficient computational power (see password strength and password cracking for more discussion). Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if anyone, may be eavesdropping on the interaction. Choosing keys used by cryptographic algorithms is somewhat different in that any pattern whatsoever should be avoided, as any such pattern may provide an attacker with a lower effort attack than brute force search. This implies random key choice to force attackers to spend as much effort as possible; this is very difficult in principle and in practice as well. As a general rule, any software except a cryptographically secure pseudorandom number generator (CSPRNG) should be avoided.
