<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _

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.

The CngAlgorithm class is a utility class. It consists of static properties, comparison methods, and a private, internally maintained, algorithm name string.

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

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

Several Cryptography Next Generation (CNG) classes (such as CngKey) accept CngAlgorithm objects through an algorithm parameter. When the class receives the CngAlgorithm object, it retrieves the embedded algorithm name by calling the object's Algorithm property.

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
