Shift Carry File Encryptor/Decryptor

I Know this is maybe a stupid idea but i made a encryptor that do shift carry operations on every bytes on the file.

Usage:

Input	Direction	Nb of iterations	Output file (optional)	Inverse output (optional, false by default)
File path or String value	"left" or "right"	1-7	A file path	"true" or "false"

Warning:

If output_file is not set then if the input is a file path then it replace it and if it's a string input then it just output it in the console...

Tip:

If you want to decrypt a file you need to do the inverse operations to encrypt (logic)

Ex:

To encrypt...:

shift_carry_encryptor foo.txt left 2 bar.txt

To decrypt...:

shift_carry_encryptor bar.txt right 2 foo.txt

How it works

The Shift Carry Encryptor*(SCE in short)* have 2 steps of bit manipulation per bytes in the input:

1. Invert the byte If Inverse Output is set to true in the arguments! (e.g: 0110 -> 1001)
2. Shift Carry depending in the direction given (e.g: Shift carry left 1 -> 1001 -> 0011 | Shift carry right 1 -> 1101 -> 1110)
