AlgorithmIdentifier Class

The AlgorithmIdentifier class defines the algorithm used for a cryptographic operation.


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

[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class AlgorithmIdentifier

The AlgorithmIdentifier type exposes the following members.

Public methodAlgorithmIdentifier()The AlgorithmIdentifier() constructor creates an instance of the AlgorithmIdentifier class by using a set of default parameters.
Public methodAlgorithmIdentifier(Oid)The AlgorithmIdentifier(Oid) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier.
Public methodAlgorithmIdentifier(Oid, Int32)The AlgorithmIdentifier(Oid, Int32) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier and key length.

Public propertyKeyLengthThe KeyLength property sets or retrieves the key length, in bits. This property is not used for algorithms that use a fixed key length.
Public propertyOidThe Oid property sets or retrieves the Oid object that specifies the object identifier for the algorithm.
Public propertyParametersThe Parameters property sets or retrieves any parameters required by the algorithm.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)


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.
