PBKDF1 - Derive Key from Password

See more Encryption Examples

Demonstrates how to derive a symmetric encryption key from a password using PBKDF1. This example matches the results found at this URL: http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

It also matches the output produced by the .NET Framework using this C# code:

            byte[] salt = new byte[] { 0x78, 0x57, 0x8E, 0x5A, 0x5D, 0x63, 0xCB, 0x06 };
            PasswordDeriveBytes cdk = new PasswordDeriveBytes("password", salt);

            cdk.IterationCount = 1000;
            cdk.HashName = "SHA1";

            // generate a 16-byte key
            byte[] key = cdk.GetBytes(16);

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();

  // http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

  final pw = 'password';
  final pwCharset = 'ansi';
  // Hash algorithms may be: sha1, md2, md5, etc.
  final hashAlg = 'sha1';
  // The salt should be 8 bytes:
  final saltHex = '78578E5A5D63CB06';
  final iterationCount = 1000;
  // Derive a 128-bit key from the password.
  final outputBitLen = 128;

  // The derived key is returned as a hex or base64 encoded string.
  // (Note: The salt argument must be a string that also uses
  // the same encoding.)
  final enc = 'hex';

  final hexKey = crypt.pbkdf1(pw, pwCharset, hashAlg, saltHex, iterationCount, outputBitLen, enc);

  print(hexKey);

  // The output should have this value:
  // DC19847E05C64D2FAF10EBFB4A3D2A20
