• sudo make install

3)Install the files of library in QT installation folder

copy all the installed files in the system to the respective QT folders

To link library in GCC(or G++) use the following code g++ -DNDEBUG -g3 -O2 -Wall -Wextra -o AES AES.cpp -l:libcryptopp.a

NOTE: AES is the executable file created and AES.cpp is the source file to be mentioned

PART 3-The Main Code

1. The ServerQT and ClientQT folder consist of the basic Socket Client and Server model:

• To Run the code execute the ServerQT file first and click on start connection.
• Then following server execute the client then start the client connection.
• Now,starting from the client side 1st message is sent then server (first recieves the message from client ) sends message, pattern is repeated.
• Messing up the message pattern will cause the problems.

/* compiling program using g++ in terminal: g++ -DNDEBUG -g3 -O2 -Wall -Wextra -o AES AES.cpp -l:libcryptopp.a executing c++ program : ./AES */
