Beispiel

Im folgenden Codebeispiel werden Daten unter Verwendung der DSACryptoServiceProvider-Klasse signiert.

Try
    'Create a new instance of DSACryptoServiceProvider.
    Dim DSA As New DSACryptoServiceProvider()

    'The hash to sign.
    Dim Hash As Byte() = {59, 4, 248, 102, 77, 97, 142, 201, 210, 12, 224, 93, 25, 41, 100, 197, 213, 134, 130, 135}

    'Sign the hash.
    Dim SignedHash As Byte() = DSA.CreateSignature(Hash)


Catch e As CryptographicException
    Console.WriteLine(e.Message)
End Try

try
{
    //Create a new instance of DSACryptoServiceProvider.
    DSACryptoServiceProvider DSA = new DSACryptoServiceProvider();

    //The hash to sign.
    byte[] Hash = {59,4,248,102,77,97,142,201,210,12,224,93,25,41,100,197,213,134,130,135};
    
    //Sign the hash.
    byte[] SignedHash = DSA.CreateSignature(Hash);


}
catch(CryptographicException e)
{
    Console.WriteLine(e.Message);
}

try
{
   //Create a new instance of DSACryptoServiceProvider.
   DSACryptoServiceProvider^ DSA = gcnew DSACryptoServiceProvider;
   
   //The hash to sign.
   array<Byte>^ Hash = { 59, 4, 248, 102, 77, 97, 142, 201, 210, 12,
                         224, 93, 25, 41, 100, 197, 213, 134, 130, 135};
   
   //Sign the hash.
   array<Byte>^ SignedHash = DSA->CreateSignature( Hash );
}
catch ( CryptographicException^ e ) 
{
   Console::WriteLine( e->Message );
}

try {
    // Create a new instance of DSACryptoServiceProvider.
    DSACryptoServiceProvider dsa = new DSACryptoServiceProvider();

    // The hash to sign.
    ubyte hash[] =  { 59, 4, 248, 102, 77, 97, 142, 201, 210,
        12, 224, 93, 25, 41, 100, 197, 213, 134, 130, 135 };

    // Sign the hash.
    ubyte signedHash[] = dsa.CreateSignature(hash);
}
catch (CryptographicException e) {
    Console.WriteLine(e.get_Message());
}
