(C# UWP/WinRT) WPA Key Calculation from PassPhrase to Hex

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

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

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

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

string wpaHexKey;

// 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";

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

Debug.WriteLine(wpaHexKey);
