Xor encryption and decryption algorithm

Overview

Folosire:

Pentru encriptare:

python encrypt.py 
    
     
     

     
    
   

Pentru decriptare:

python decrypt.py 
    
     
     

     
    
   

Explicații:

Pentru o criptare eficientă a textului din fișierul de intrare am criptat caracter cu caracter folosind operația pe biți xor(^), astfel:

crypt[i] = text[i] ^ parola[i % lungimea_parolei]

Pentru decriptare a fost folosită aceeași metodă.

Gestionarea erorilor:

Programul va returna în consolă următoarele mesaje în cazul în care întâlnește erori:

"Numar de argumente incorect!" - Nu a fost transmis numărul corect de parametrii

"Parola invalida" - Parola transmisă nu are între 10 și 15 caractere

"Fisier de citire inexistent" - Fișierul ce va trebui citit nu se află în folderul script-ului
