Verify that the
configuration
properties of the
providers are
exposed as public
and that they are
strongly typed.
Yes
In the CryptographySettings class, the SymmetricProviders
property can only contain a SymmetricProvider-
Data collection. The following code demonstrates this.
The HashProviders property is similar.
[ConfigurationProperty(symmetricCryptoProvider
sProperty, IsRequired= false)]
public NameTypeConfigurationElementCollection<
SymmetricProviderData> SymmetricCryptoProviders
{
}
Verify that the
configuration properties
for the custom
providers are
exposed as public
and that they are
implemented as
custom property
collections.
Verify that there is
a way to remove
decrypted keys
from memory after
they have been
used.
Yes
Yes
The CustomSymmetricCryptoProviderData class
and the CustomHashProviderData class have references
to the CustomProviderDataHelper class. This
class defines a NameValueCollection class that holds
the attributes in custom property collections. This is
shown in the following code example.
private NameValueCollection attributes;
private void AddAttributesFromConfigurationProperties()
{
foreach (ConfigurationProperty property in
propertiesCollection)
{
…
attributes.Add(property.Name, (string)helped
CustomProviderData.BaseGetPropertyValue(prop
erty));
}
}
The CryptographicUtility.ZeroOutBytes method clears
the decrypted key from memory. This is shown in the
following code example.
public byte[] Encrypt(…)
{
CryptographyUtility.ZeroOutBytes(this.algorithm.Key);
}
