WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

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

//  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);
