Verify that the
Cryptographer
façade uses the
SymmetricCryptoProviderFactory
class and the
HashProviderFactory
class to create
the cryptography
providers.
Yes
The client code calls static methods on the Cryptographer
class to create hashes, compare hashes, encrypt
data, and decrypt data. Each static method instantiates
a factory class and passes the configuration
source to the factory class’s constructor. The factory
uses the configuration data to determine the type of
provider to create. The following code demonstrates
how the Cryptographer.EncryptSymmetric method
calls the SymmetricCryptoProviderFactory class to
create a symmetric provider. The process is similar for
hash providers.
public static byte[] EncryptSymmetric(string
symmetricInstance, byte[] plaintext)
{
…
SymmetricCryptoProviderFactory factory = new
SymmetricCryptoProviderFactory(ConfigurationSo
urceFactory.Create());
…
}
Verify that assembler
classes
that implement
the IAssembler
interface create
the symmetric and
hash providers,
and inject the configuration
object
values into those
domain objects.
Yes
The following code demonstrates how the SymmetricAlgorithmProviderAssember
class, which implements
the IAssembler interface, creates a symmetric
provider. The process is similar for hash providers.
public class SymmetricAlgorithmProviderAssembler
: IAssembler
{
public ISymmetricCryptoProvider
Assemble(IBuilderContext context, SymmetricProviderData
objectConfiguration, IConfigurationSource
configurationSource, ConfigurationReflectionCache
reflectionCache)
{
SymmetricAlgorithmProviderData castedObject-
Configuration = (SymmetricAlgorithmProviderDat
a)objectConfiguration;
ISymmetricCryptoProvider createdObject = new
SymmetricAlgorithmProvider(castedObjectConfigu
ration.AlgorithmType,
castedObjectConfiguration.ProtectedKeyFilename
,castedObjectConfiguration.ProtectedKeyProtectionScope);
return createdObject;
}
}
