C++ Cryptlib

Merhaba Arkadaslar,
Türkcem biraz kitdir, kusurabakmayin.

Benim Projem de, bir Smartcardlan bir file li Signature edmeliyim.

Peter Guttman'in Cryptlib len calisiyorum.

Bu liblen calisan oldugsa bana insallah yardim edebillir.

Hata [CODE]cryptgetPrivatekey[/CODE] 4. parameter ne oldugunu tam anlamadim

Source Codum su

[CODE]#include <iostream>

Sagol yardimlariniz icin

hata derleme zaman1nda oluyorsa, 4. parametrede tür uyumsuzlugu vard1r, neden oraya içi bos bir string veriyorsun?

Pardon görmemisim hata ama source da degil hata Smartcard daydi smartcarda iki tane ayni ismili PrivateKey vardi. O hatayi cösdüm simdi ama baska problemim var.
