PBKDF2 - Derive Key from Password

Demonstrates how to derive a symmetric encryption key from a password using PBKDF2. This example matches the results found at this URL: http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

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

bool success;
success = crypt.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(crypt.LastErrorText);
    return;
}

string hexKey;

string pw;
pw = "password";
string pwCharset;
pwCharset = "ansi";
//  Hash algorithms may be: sha1, md2, md5, etc.
string hashAlg;
hashAlg = "sha1";
//  The salt should be 8 bytes:
string saltHex;
saltHex = "78578E5A5D63CB06";
int iterationCount;
iterationCount = 2048;
//  Derive a 192-bit key from the password.
int outputBitLen;
outputBitLen = 192;

//  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;
enc = "hex";

hexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,saltHex,iterationCount,outputBitLen,enc);

textBox1.Text += hexKey + "\r\n";

//  The output should have this value:
