How to Include OpenSSL in a Qt project

by

Assuming Windows, you can download its installation from Win32 OpenSSL Installation Project page. You can choose one for 64-bit windows developing or for 32-bit. Just run the setup and everything will be done easily. The default installation directory is : C:\OpenSSL-Win32
In Qt creator, if you then want to link a library to your project you can just add this line to your .pro file(project file ) : 

LIBS += -L/path/to -llibname

So here’s what we do for this library( for example to link ubsec.lib )

LIBS += -LC:/OpenSSL-Win32/lib -lubsec

Pay attention to -L and -l.See this question. You don’t even need to specify .lib at the end of the library name.

For including .h files add this line to your .pro file : 

INCLUDEPATH += C:/OpenSSL-Win32/include

after that you can include a file like this :

#include <openssl/aes.h>
