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

public CspParameters(
	int providerType,
	string providerName,
	string keyContainerName,
	CryptoKeySecurity cryptoKeySecurity,
	IntPtr parentWindowHandle
)

Parameters

providerType
Type: System.Int32

The provider type code that specifies the kind of provider to create.

providerName
Type: System.String

A provider name.

keyContainerName
Type: System.String

A container name.

cryptoKeySecurity
Type: System.Security.AccessControl.CryptoKeySecurity

An object that represents access rights and audit rules for the container.

parentWindowHandle
Type: System.IntPtr

A handle to the parent window for a smart card password dialog.

You can use the container name to retrieve a key within that container.

Specify a provider type by passing a numeric value that represents the desired provider type. The numeric values that represent the default provider types are defined in the WinCrypt.h header file:

  • To specify a provider compatible with the RSA algorithm, pass a value of 1to the dwTypeIn parameter.

  • To specify a provider compatible with the DSA algorithm, pass a value of 13to the dwTypeIn parameter.

For information about other provider type values, see the ProviderType field. For more information about the default provider types and their behaviors, see the Microsoft Cryptography API (CAPI) documentation in the MSDN library.
