Pozdrav svima.

Sta sa nizom nije dovoljno "long"?

Pozzzz

Kada konvertuješ Settings.Serial u ASCII niz bajtova, dobijaš niz duži od 16 elemenata.
Rešenje - ili skrati vrednost Settings.Serial ili proširi byteSerial.

Code:

public static CryptoStream GetCryptoReadStream( Stream stream )
        {
            ICryptoTransform encryptor;
            Byte[] byteName;
            Byte[] byteSerial;

            byteName=new Byte[32];
            byteName.Initialize();

            byteSerial=new Byte[16];
            byteSerial.Initialize();

            Array.Copy(Encoding.ASCII.GetBytes(Settings.Name),0,byteName,0,
                Math.Min(Encoding.ASCII.GetBytes(Settings.Name).Length,32));
            Array.Copy(Encoding.ASCII.GetBytes(Settings.Serial),0,byteSerial,0,16);

            RijndaelManaged rm;
            rm=new RijndaelManaged();

            encryptor=rm.CreateDecryptor(byteName,byteSerial);

            CryptoStream cryptoStream;
            cryptoStream=new CryptoStream(stream,encryptor,CryptoStreamMode.Read);

            return cryptoStream;
        }

Code:
byteSerial = new Byte[32];

Je li dovoljno ovde reći da je byteSerial sada dužine 32?

Hvala puno na savetu.

Ovo sto sam sam sebi predložio ne radi. Tj opet exception

Re: Source array was not long enough. 27.01.2016. u 17:05 · pre 130 meseci #5

Code:

Array.Copy(Encoding.ASCII.GetBytes(Settings.Serial),0,byteSerial,0,
Math.Min(Encoding.ASCII.GetBytes(Settings.Serial).Length,16));

Izvini ako sam te razumeo. Kazes ovo:

Code:

Array.Copy(Encoding.ASCII.GetBytes(Settings.Name),0,byteName,0,
Math.Min(Encoding.ASCII.GetBytes(Settings.Name).Length,32));

Array.Copy(Encoding.ASCII.GetBytes(Settings.Serial),0,byteSerial,0,16);

da napisem ovako:

Code:

Array.Copy(Encoding.ASCII.GetBytes(Settings.Serial),0,byteSerial,0,
Math.Min(Encoding.ASCII.GetBytes(Settings.Serial).Length,16));

Array.Copy(Encoding.ASCII.GetBytes(Settings.Serial),0,byteSerial,0,16);

Ne razumem bas ovo :(

Džaba, probao sam i ovo prethodno i menjao dužinu niza byteSerial uvek ista greška.
