示例1: ContosoDeformatter
//引入命名空间
using System;
using System.Security.Cryptography;
namespace Contoso
{
public class ContosoDeformatter : AsymmetricKeyExchangeDeformatter
{
private RSA rsaKey;
// Default constructor.
public ContosoDeformatter(){}
// Constructor with the public key to use for encryption.
public ContosoDeformatter(AsymmetricAlgorithm key)
{
SetKey(key);
}
// Set the public key for encyption operations.
public override void SetKey(AsymmetricAlgorithm key) {
if (key != null)
{
rsaKey = (RSA)key;
}
else
{
throw new ArgumentNullException("key");
}
}
// Disallow access to the parameters of the formatter.
public override String Parameters
{
get { return null; }
set { ; }
}
// Create the encrypted key exchange data from the specified input
// data. This method uses the RSACryptoServiceProvider only. To
// support additional providers or provide custom decryption logic,
// add logic to this member.
public override byte[] DecryptKeyExchange(byte[] rgbData) {

if (rsaKey != null)
{

{

}
// Add custom decryption logic here.
}
else
{
throw new CryptographicUnexpectedOperationException(
"Cryptography_MissingKey");
}
return decryptedBytes;
}
}
}
//输出：
