How To: Create an Encryption Library 437
2. Create a Console Test Application
This procedure creates a simple console test application to test the encryption and
decryption functionality.
To create a console test application
1. Add a new C# Console application called EncryptionTester to the current
solution.
2. In Solution Explorer, right-click the EncryptionTester project, and then click Set
as StartUp Project.
3. Use Solution Explorer to rename class1.cs as EncryptionTest.cs.
4. In EncryptionTest.cs, rename Class1 as EncryptionTest.
5. Add a project reference to the Encryption project.
6. Add the following using statements at the top of EncryptionTest.cs.
using System.Text;
using Encryption;
7. Add the following code to the Main method.
// Set the required algorithm
EncryptionAlgorithm algorithm = EncryptionAlgorithm.Des;
// Init variables.
byte[] IV = null;
byte[] cipherText = null;
byte[] key = null;
try
{ //Try to encrypt.
//Create the encryptor.
Encryptor enc = new Encryptor(EncryptionAlgorithm.Des);
byte[] plainText = Encoding.ASCII.GetBytes("Test String");
if ((EncryptionAlgorithm.TripleDes == algorithm) ||
(EncryptionAlgorithm.Rijndael == algorithm))
{ //3Des only work with a 16 or 24 byte key.
key = Encoding.ASCII.GetBytes("password12345678");
if (EncryptionAlgorithm.Rijndael == algorithm)
{ // Must be 16 bytes for Rijndael.
IV = Encoding.ASCII.GetBytes("init vec is big.");
}
else
{
IV = Encoding.ASCII.GetBytes("init vec");
}
}
