I found a good Passphrase to WEP converter at WEPKEY.COM - Wireless Encryption Protocol WEP Key Generator - Lost WEP Key Convertor (http://www.wepkey.com)
Is their something that converts the other way? WEP to passphrase?

The javascript code used for the generator is in the source of the page you linked. The 128 bit key looks like it is hashed with MD5. That, I think, would have to be brute forced to go the other way which is not a click-the-button-and-instantly-get-result endeavor.

The book How Secure is Your Wireless Network? Safeguarding Your Wi-Fi LAN by Lee Barkin discusses some of the disadvantages of using key generators instead of manual keying.

Thanks, The generator is not Random, I would think, it was like multiplying one way, the to convert the other way would be divide so to speak.
