![]() ![]() | ECDiffieHellmanP256 | Gets a CngAlgorithm object that specifies an Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm that uses the P-256 curve. |
![]() ![]() | ECDiffieHellmanP384 | Gets a CngAlgorithm object that specifies an Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm that uses the P-384 curve. |
![]() ![]() | ECDiffieHellmanP521 | Gets a CngAlgorithm object that specifies an Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm that uses the P-521 curve. |
![]() ![]() | ECDsaP256 | Gets a CngAlgorithm object that specifies an Elliptic Curve Digital Signature Algorithm (ECDSA) that uses the P-256 curve. |
![]() ![]() | ECDsaP384 | Gets a CngAlgorithm object that specifies an Elliptic Curve Digital Signature Algorithm (ECDSA) that uses the P-384 curve. |
![]() ![]() | ECDsaP521 | Gets a new CngAlgorithm object that specifies an Elliptic Curve Digital Signature Algorithm (ECDSA) that uses the P-521 curve. |
![]() ![]() | MD5 | Gets a new CngAlgorithm object that specifies the Message Digest 5 (MD5) hash algorithm. |
![]() ![]() | Sha1 | Gets a new CngAlgorithm object that specifies the Secure Hash Algorithm 1 (SHA-1) algorithm. |
![]() ![]() | Sha256 | Gets a new CngAlgorithm object that specifies the Secure Hash Algorithm 256 (SHA-256) algorithm. |
![]() ![]() | Sha384 | Gets a new CngAlgorithm object that specifies the Secure Hash Algorithm 384 (SHA-384) algorithm. |
![]() ![]() | Sha512 | Gets a new CngAlgorithm object that specifies the Secure Hash Algorithm 512 (SHA-512) algorithm. |
| Name | Description | |
|---|---|---|
![]() | Equals(CngAlgorithm) | Compares the specified CngAlgorithm object to the current CngAlgorithm object. |
![]() | Equals(Object) | Compares the specified object to the current CngAlgorithm object. (Overrides Object::Equals(Object).) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Generates a hash value for the algorithm name that is embedded in the current CngAlgorithm object. (Overrides Object::GetHashCode().) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Gets the name of the algorithm that the current CngAlgorithm object specifies. (Overrides Object::ToString().) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equality | Determines whether two CngAlgorithm objects specify the same algorithm name. |
![]() ![]() | Inequality | Determines whether two CngAlgorithm objects do not specify the same algorithm. |
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.

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. |
