Mar 24, 2007 In the meantime, there are websites devoted to telling you how to generate random keys at home, as well as some sites that generate various WEP keys for you. This page will generate a wpa-psk of whatever size you like, safely and securely. (Plus you don't have to roll a die a couple hundred times.) How does this page work? NOTE 1: If the WPA Pre-Shared Key appears as dots, then check the Show Key below it to reveal the key. NOTE 2: If the WPA Pre-Shared Key is greyed out, skip down to the To Change the WEP Key section of this document. For the WPA Pre-Shared Key, enter a new key to use. The WPA key must be 8 - 63 characters. NOTE 1: If the WPA Pre-Shared Key appears as dots, then check the Show Key below it to reveal the key.

Techopedia explains Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) WPA-PSK works by configuring a WLAN passphrase or password of eight to 63 characters. Based on the password, access point (router) and connecting node credentials, a 256-character key is generated, shared and used by both devices for network traffic encryption and decryption. When these passwords are used to generate pre-shared keys for protecting WPA WiFi and VPN networks, the only known attack is the use of 'brute force' — trying every possible password combination. Brute force attackers hope that the network's designer (you) were lazy and used a.

PSK Generator provides a secure process to negotiate a 64-byte IPsec Pre-Shared Key (also known as a Shared Secret or PSK) through insecure means, such as email.

Instructions:

You and your VPN partner will use two separate passwords to create a unique 64-byte shared secret with the help of a cryptographic hash generator. Regardless of the length of each password, the generated Shared Secret will always be 64 bytes.

1) Create a list of at least 10 randomly generated passwords. These passwords should be at least 64 characters long. Email the password list to your VPN partner, but do NOT include these instructions, this website address, or anything else in the email that reveals the process that is about to be used.

Hint: Click on the keyhole of the padlock picture above to get a list of 32 cryptographically strong random passwords.

2) Over the phone, provide your VPN partner this website address and have them pick one of the passwords from the list you emailed to them. Both of you will copy and paste the selected password to the Password Seed box.

3) Give your VPN partner a simple shorter password. I suggest a 16-digit numeric string as this would be easy to share over the phone with a reduced chance of mistakes. Both of you will enter this shorter passsword in the Key box.

4) Both of you will click the Generate button. Verify the first and last 2 or 3 bytes over the phone to ensure you've created the same Shared Secret.

5) Copy and paste the Shared Secret to your VPN configuration.

Alternate Method: Both parties use a random password generator to create a list of 10 or more long passwords and email them to each other. On the phone, decide which password from one of the lists to use as the Password Seed and which password from the other list for the Key.
