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.

This class wraps NCrypt keys, not BCrypt keys. NCrypt is a subset of CNG that provides key storage functionality. BCrypt is a subset that provides base cryptographic services such as random number generation, hash functions, signatures, and encryption keys.
