WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

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

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var crypt = new CkCrypt2();

var wpaHexKey;

// The "ps" is the WPA passphrase
var pw = "password";
var pwCharset = "ansi";

// 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"
var ssidHex = "414243";

// The WPA key calculation will always use 4096 iterations.
var iterationCount = 4096;

// The WPA hex output should be 256 bits.
var outputBitLen = 256;

// Indicate that "hex" is to be returned.
var enc = "hex";

wpaHexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,ssidHex,iterationCount,outputBitLen,enc);

console.log(wpaHexKey);
