KeyNumber Enumeration
Visual Studio 2010
Specifies whether to create an asymmetric signature key or an asymmetric exchange key.
Assembly: mscorlib (in mscorlib.dll)
| Member name | Description | |
|---|---|---|
| Exchange | An exchange key pair used to encrypt session keys so that they can be safely stored and exchanged with other users. This value corresponds to the AT_KEYEXCHANGE value used in the unmanaged Microsoft Cryptographic API (CAPI). | |
| Signature | A signature key pair used for authenticating digitally signed messages or files. This value corresponds to the AT_SIGNATURE value used in the unmanaged Microsoft Cryptographic API (CAPI). |
The following code example demonstrates how to use the KeyNumber enumeration to specify a key type for an RSACryptoServiceProvider object.
// Create a new CspParameters object. CspParameters^ cspParams = gcnew CspParameters(); // Specify an exchange key. cspParams->KeyNumber = (int) KeyNumber::Exchange; // Initialize the RSACryptoServiceProvider // with the CspParameters object. RSACryptoServiceProvider^ RSACSP = gcnew RSACryptoServiceProvider(cspParams);
