Testing the Cryptography Application Block 53
Test case Result Automated test
Verify that a
custom class can
be added from
information in
the configuration
source.
Passed
In this example, a custom hash provider, the Custom Hash
class, implements the IHashProvider interface. The Enterprise
Library Core uses information in the configuration
source to add the custom class to the application block.
CustomHash class
[ConfigurationElementType(typeof(CustomHashProvid
erData))]
public class CustomHash:IHashProvider
{
public NameValueCollection ObjCol;
public CustomHash(NameValueCollection obj)
{
this.ObjCol = obj;
}
byte[] CreateHash(byte[] plaintext){…}
bool CompareHash(byte[] plaintext, byte[]
hashedtext){…}
}
The following is the information in the configuration file.
The following is the test case.
[TestMethod]
public void TestCustomHash()
{
HashProviderFactory factory = new
HashProviderFactory(new SystemConfiguration-
Source());
IHashProvider provider = factory.
Create("CustomHash1");
Assert.IsNotNull(provider);
Assert.IsTrue(provider is CustomHash);
}
