CngKeyBlobFormat Class

Specifies a key BLOB format for use with Microsoft Cryptography Next Generation (CNG) objects.

Namespace:  System.Security.Cryptography
Assembly:  System.Core (in System.Core.dll)

public final class CngKeyBlobFormat implements IEquatable<CngKeyBlobFormat>

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 CngKeyBlobFormat class is a utility class. It consists of static properties, comparison methods, and a private, internally maintained string that specifies the key BLOB format name.

The static properties return CngKeyBlobFormat objects. Each object's internal string name is initialized to the key BLOB format name that corresponds to the name of the static property.

You can also use this class to create objects for key BLOB formats that are not covered by the static properties.

Several CNG classes (such as CngKey) accept CngKeyBlobFormat objects through a format parameter. When the class receives the CngKeyBlobFormat object, it retrieves the embedded name of the key BLOB format by calling the object's Format property.

Therefore, CngKeyBlobFormat serves as an enumeration of well-known key BLOB formats. It lets you identify a well-known key BLOB format by using a strongly typed value instead of a string.
