Compare Chilkat 3DES Results with .NET Triple-DES Results

This C# example program demonstrates how the Chilkat 3DES implementation produces the same results as the .NET Framework implementation of 3DES.

The TripleDesEncryptOneBlock method, which uses the .NET TripleDESCryptoServiceProvider class can be found here.

        // Compare Chilkat 168-bit 3DES results with .NET's 3DES results.
        public void CompareTripleDes()
        {
            Chilkat.Crypt2 crypt = new Chilkat.Crypt2();
	
            bool success;
            success = crypt.UnlockComponent("Anything for 30-day trial");
            if (success != true)
            {
                MessageBox.Show("Crypt component unlock failed");
                return;
            }
	
            // Set the encryption algorithm to 168-bit 3DES (Electronic Cookbook Mode):
            // Note: We still use the string "des" for the algorithm.
            // The KeyLength of 168 indicates that it's really Triple-DES.
            crypt.CryptAlgorithm = "des";
            crypt.KeyLength = 168;
            crypt.CipherMode = "ecb";
            // PAD with NULLs.  If input is already a multiple of the block size (8 bytes), then no padding is added.
            // This will be the case here, so there is no padding..
            crypt.PaddingScheme = 3;
	
            int i;
            for (i = 0; i < 16; i++)
            {
                // Get 24 bytes of key and 8 bytes of plain-text.
                byte[] key = Get24RandomBytes();
                byte[] plainText = GetRandomBytes();
	
                // Encrypt using .NET:
                byte[] dnEncrypted = TripleDesEncryptOneBlock(plainText, key);
	
                // Encrypt using Chilkat:
                crypt.SecretKey = key;
                byte[] ckEncrypted = crypt.EncryptBytes(plainText);
	
                // Encode to a hex string and display for comparison:
                string dnHex = crypt.Encode(dnEncrypted, "hex");
                string ckHex = crypt.Encode(ckEncrypted, "hex");
	
                string keyHex = crypt.Encode(key, "hex");
                string plainTextHex = crypt.Encode(plainText, "hex");
	
                textBox1.Text += "key=" + keyHex + " , pt=" + plainTextHex + "\r\n";
                textBox1.Text += "enc=" + dnHex + " = " + ckHex + "\r\n\r\n";
            }
	
        }
