I följande kodexempel visas hur du skapar en ny instans av CipherData klassen. Hela exemplet finns i klassavsnittet CipherData .

// Create a new CipherData object.
CipherData cd = new CipherData();
// Assign a byte array to be the CipherValue. This is a byte array representing encrypted data.
cd.CipherValue = new byte[8];

' Create a new CipherData object.
Dim cd As New CipherData
' Assign a byte array to the CipherValue.
cd.CipherValue = New Byte(7) {}
