About the encryption method

I am using api cryptography encryption function (fun is declared as virtual)

//fun declaration
TBool EncryptL(const TDesC8 &aInput, TDes8 &aOutput);

//function calling
TBuf8<10> text;
TBuf8<10> cipher;
text.Copy(_L("Hello"));
iEncryptor.EncryptL(text,cipher); it shows error expression syntax error

//fun definition
TBool CRSAAlgo::EncryptL(const TDesC8 &aInput,TDes8 &aOutput) 
{
    if(iEncryptor)
    {
        TInt len = iEncryptor->MaxInputLength();
    }
}

I want to know what the exact problem is

The main problem here, the reason your compiler is complaining is that you are using iEncryptor as an object or reference, while it is probably a C ++ pointer.

To move on to the next step, try using:



iEncryptor-> EncryptL (text, cipher);

Since you haven't posted the exact error message you are getting from the compiler, I have to guess.

I guess the problem is that the EncryptL function you are showing is expecting to receive arguments of type TDesC8 and you are passing TBuf8 <10> to it. If TDesC8 was not a typedef for TBuf8 <10, then they are different and therefore for incompatible compiler types.



Ypou also uses iEncryptor once as a pointer: iEncryptor-> MaxInputLength (); and in the place where you see the error as an object: iEncryptor.EncryptL (text, cipher) ;. Only one shape can be correct. Since we don't have any more code from you, I don't know what, but given the fact that the latter has a bug, I suspect the latter.
