(C#) PBKDF1 - Derive Key from Password

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);

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

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

hexKey = crypt.Pbkdf1(pw,pwCharset,hashAlg,saltHex,iterationCount,outputBitLen,enc);

Debug.WriteLine(hexKey);

// The output should have this value:
