CspParameters Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Contains parameters that are passed to the cryptographic service provider (CSP) that performs cryptographic computations. This class cannot be inherited.

Syntax

'Declaration
Public NotInheritable Class CspParameters

public sealed class CspParameters

The CspParameters type exposes the following members.

Constructors

	Name	Description
	CspParameters()	Initializes a new instance of the CspParameters class.
	CspParameters(Int32)	Initializes a new instance of the CspParameters class with the specified provider type code.
	CspParameters(Int32, String)	Initializes a new instance of the CspParameters class with the specified provider type code and name.
	CspParameters(Int32, String, String)	Initializes a new instance of the CspParameters class with the specified provider type code and name, and the specified container name.

Properties

	Name	Description
	Flags	Represents the flags for CspParameters that modify the behavior of the cryptographic service provider (CSP).

Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	KeyContainerName	Represents the key container name for CspParameters.
	KeyNumber	Specifies whether an asymmetric key is created as a signature key or an exchange key.
	ProviderName	Represents the provider name for CspParameters.
	ProviderType	Represents the provider type code for CspParameters.

Remarks

The CspParameters class represents parameters that you can pass to managed cryptography classes that internally use Microsoft Cryptographic Service Providers (CSPs) from the unmanaged Microsoft Cryptography API (CAPI). Classes with names ending in "CryptoServiceProvider" are managed code wrappers for the corresponding CSP.

Use the CspParameters class to do the following:

Specify a particular CSP by passing the provider type to the ProviderType or ProviderName property. You can also specify a CSP using an overload of the constructor.
Create a key container where you can store cryptographic keys. Key containers provide the most secure way to persist cryptographic keys and keep them secret from malicious third parties.
Specify whether to create an asymmetric signature key or an asymmetric exchange key using the KeyNumber property.
