Fields
| Name | Value | Description |
|---|---|---|
| Exchange | 1 | 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 | 2 | 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). |
Examples
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);
// Create a new CspParameters object.
CspParameters cspParams = new CspParameters();
// Specify an exchange key.
cspParams.KeyNumber = (int) KeyNumber.Exchange;
// Initialize the RSACryptoServiceProvider
// with the CspParameters object.
RSACryptoServiceProvider RSACSP = new RSACryptoServiceProvider(cspParams);
' Create a new CspParameters object.
Dim cspParams As New CspParameters()
' Specify an exchange key.
cspParams.KeyNumber = Fix(KeyNumber.Exchange)
' Initialize the RSACryptoServiceProvider
' with the CspParameters object.
Dim RSACSP As New RSACryptoServiceProvider(cspParams)
Remarks
Use the KeyNumber enumeration with the CspKeyContainerInfo.KeyNumber property to inspect a key type or with the CspParameters.KeyNumber field to specify a key type.
