示例1: DecryptKeyExchange

' 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 Overrides Function DecryptKeyExchange(
    ByVal rgbData() As Byte) As Byte()

    Dim decryptedBytes() As Byte

    If (Not rsaKey Is Nothing) Then
        If (TypeOf (rsaKey) Is RSACryptoServiceProvider) Then
            Dim rsaProvider As RSACryptoServiceProvider
            rsaProvider = CType(rsaKey, RSACryptoServiceProvider)

            decryptedBytes = rsaProvider.Decrypt(rgbData, True)
        End If

        ' Add custom decryption logic here.

    Else
        Throw New CryptographicUnexpectedOperationException(
            "Cryptography_MissingKey")
    End If

    Return decryptedBytes
End Function
