C++ Implementation of Skinny cipher

This repository contains simple C++ implementations of the following ciphers:

• Skinny-64-128
• Skinny-64-192
• Skinny-128-256
• Skinny-128-384

Building

In order to build this project, just type the following command:

make

Usage

Open the terminal inside the skinny folder, and then call the object file corresponding to the target cipher. For example, in order to doing encryption via the skinny-64-128, type the following command:

./skinny-64-128.o

Test-Vectors

It is supposed that the state array is filled according to the following order:
