[C++] Simple C++ encryption and decryption algorithm

principle

Utilizing the symmetry of bit XOR calculations, appkey and appsecret are used to perform XOR calculations to achieve encryption and decryption effects.

encryption

std::wstring EncryptData(std::wstring& data)
    {
    
    
        for (int i = 0; i < data.size(); ++i)
        {
    
    
            int keyIndex    = i % sc_ConfigEncryptKey.size();
            int secretIndex = i % sc_ConfigEncryptSecret.size();
            data[i]         = data[i] ^ sc_ConfigEncryptKey[keyIndex];
            data[i]         = data[i] ^ sc_ConfigEncryptSecret[secretIndex];
        }
        return data;
    }

Decrypt

std::wstring DecryptData(std::wstring& data) 
    {
    
    
        return EncryptData(data);
    }
