SarBaste

SarBaste is a simple stream chiper which use two methods for encrypting or decrypting streams.

Simple Method

In this method each character of input file added to key characters sequentially.

Encryption Example:

Decryprion Example:

Complicated Method

This method like other simple stream ciphers use a psudo random generator to generate key for each characters specifically.

Encryption Example:

Decryprion Example:

How to Run?

At first, you should make executable file from code.

g++ --std=c++11 main.cpp -o sarbaste.out

Then you can run this executable and perform input like this:

./sarbaste.out
encrypt/decrypt
simple/complicated
<inputFilePath>
<outputFilePath>

For example :

./sarbaste.out
encrypt
simple
./input.txt
./output.txt
