// 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 = 2048;
// Derive a 192-bit key from the password.
int 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 = "hex";

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

Debug.WriteLine(hexKey);

// The output should have this value:
