The following test encrypts a string.
[TestMethod]
public void TestEncryptionForValidInput()
{
String encryptedStrMessage = Cryptographer.Encr
yptSymmetric(("DESCryptoServiceProvider","Sample
Text");
Assert.IsFalse(encryptedStrMessage.Equals(""));
Assert.IsFalse(encryptedStrMessage.
Equals("SampleText"));
}
The following test uses the new operator to directly create
the hash provider and verifies that the object is created.
[TestMethod]

{
HashAlgorithmProvider provider = new HashAlgorit
