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

    crypt := chilkat.NewCrypt2()

    var hexKey *string = new(string)
    // http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

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

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

    fmt.Println(*hexKey)

    // The output should have this value:
    // BFDE6BE94DF7E11DD409BCE20A0255EC327CB936FFE9364
