About

Cipher is a very basic text encryption program.

It has two high level function.

• TO ENCRYPT

  INPUT –—> Processing -—> OUTPUT

  Text file(normal) -—> encryption -–—> text file (encrypted)

• TO DECRYPT

  INPUT –—> Processing -—> OUTPUT

  Text file(encrypted) -—> decryption -–—> text file (normal)

  TLDR: We open text file do sth to each alphabet and get unreadable file (but here the catch we can undo this process!)

How user will use it

It is command line program so a terminal is needed.

• By giving our program a input file

  $ cipher input.txt
  

• Now cipher will generate output.txt in the same folder

• INTERACTIVE MODE!

  $ cipher --interactive
  

  Will launch a prompt

   Hello and welcome to cipher!
  
  >> 
  

  You can type words into the prompt and it will get encrypted!
