I\'m suppoesd to write it in c++,Linux.

I understood that I\'m supposed to use openssl/aes, but couldn

Answer 1

have a look at cryptopp. They have Rijndael (AES) "raw" and in block modes (CBC etc.). Look at their wiki documentation, they have many code samples.

It is a popular crypto library, they have also a Windows version, so you can use on both platforms. If you wish to keep your current implementation on Windows, you may want to have your custom wrapper, so that you can choose an underlying implementation on each platform.

EDIT: a sample from my code

using namespace CryptoPP;

CBC_Mode< CryptoPP::AES >::Encryption encryptor;

std::string clearText("hello world");
std::string encrypted;

StringSource( clearText, true,
    new StreamTransformationFilter( encryptor,
        new StringSink( encrypted )
    )
);
