The CngAlgorithmGroup class is a utility class. It consists of static properties, comparison methods, and a private, internally maintained string that defines an algorithm group name.

The static properties return CngAlgorithmGroup objects. Each object's internal string is initialized to the algorithm group name that corresponds to the name of the static property.

You can also use this class to create objects for algorithm groups that are not covered by the static properties.

Several Cryptography Next Generation (CNG) classes (such as CngKey) return CngAlgorithmGroup objects. Classes that receive CngAlgorithm objects can retrieve the embedded algorithm group name by calling the object's AlgorithmGroup property.

Therefore, CngAlgorithmGroup serves as an enumeration of well-known algorithm groups. It lets you specify an algorithm group name by using a strongly typed value instead of a string.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
