(Node.js) WPA Key Calculation from PassPhrase to Hex

Demonstrates how to calculate a WPA key from a passprhase and network SSID.

    // Hash algorithms may be: sha1, md2, md5, etc.
    var hashAlg = "sha1";

    // Specify the SSID in hex:
    // For example, if the SSID is "ABC", then the 
    // hex values for these us-ascii chars is "414243"
