Remarks

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.

Note

CNG classes don't work on non-Windows platforms.
