@SGaist said in best way to use AES Encryption in QT:

Are you sure that the library was built for thé same architecture as the Qt version you are using ?

i see a video in yotube use botan 1.10.8 on QT 4.8.5
you think its not support new verson of qt?

SGaist

You should use the latest version of botan for security reasons.

In any case, it's completely unrelated to my question: aare the architectures of your botan build and Qt the same ?

i check botan-ci.exe, here is result

and here is botan.dll

both is 64bit
and also my qt compiler is 64bit too

SGaist

Did you also compile botan with MinGW ?

no i compile it with nmake
i need to compile it with MiniGW?

SGaist

If you used nmake, it means that in fact you used Visual Studio to build botan. So there's your issue. You can't mix C++ code built with MinGW with C++ code built with Visual Studio.

Tow options here:

rebuild botan using MinGW
change your Qt version and use the one that matches your Visual Studio version

you recommend what version of qt for this?
i think its beter to compile botan again..

SGaist

As I said: the one matching your current version of Visual Studio.

sorry i made a mistake
I mean, which version of mingw do you recommend?

SGaist

Use the one from your Qt installation.
