WPA Key Calculation from PassPhrase to Hex

Demonstrates how to calculate a WPA key from a passprhase and network SSID. Chilkat2 Java

import com.chilkatsoft.chilkat2.Crypt2;

public class ChilkatExample {

    public static void main(String[] args) {
        // This example assumes the Chilkat API to have been previously unlocked.
        // See Global Unlock Sample for sample code.

        Crypt2 crypt = new Crypt2();

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

        // Hash algorithms may be: sha1, md2, md5, etc.
        String 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"
        String ssidHex = "414243";

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

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

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

        String wpaHexKey = crypt.pbkdf2(pw, pwCharset, hashAlg, ssidHex, iterationCount, outputBitLen, enc);
