WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

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

import 'package:chilkat/chilkat.dart';

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

  final crypt = CkCrypt2();

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

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

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

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

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

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

  print(wpaHexKey);
