This is an implementation of a Caesar Cipher. It can encrypt and decrypt files and strings using a provided key. I used Ubuntu on the Windows Subsystem for Linux to compile it using g++. This is implemented with C++14.

Download the repository. Once downloaded, compile it using the command:

make

To clean up (remove the compiled files), use

make clean

The format for the input in the command line is as follows:

./cipher <flags> <key> <arg>

flags: [-e|-d] mode: encrypt/decrypt; [-s|-f] arg is a string/filename

key: string input for encryption/decryption

arg: string/filename to encrypt/decrypt
