Simple-Terminal-Encryptor

This is a short python code to encrypt an 8 char input by displaying the charachters in even indices first followed by those in odd indexes

import time import sys import os

A function to determine the length of the input text

def lenText(): v = len(validateInput.text) print("The length is " +str(v) +" charachters.")

A function that determines whether the entered data is of the required charachter size

The assert keyword can also be used to reduce the lines of code

def validateInput(text:str): validateInput.text = text # print(text) # printing is outputting text to terminal lenText() v = len(text) # determining the length of text into a var v # print(v) if v!= 8: # an if else statement

    while v != 8:
        
        text = input("Enter text with 8 charachters:")
        validateInput.text = text
        v = len(text)
        print("Length of text:",v)
        if v ==8:  
            print("Your text is ",text," wait for encryption.") 
        else:
            print("Your text isn\'t 8 chars.")
        if len(text) != 8:
            print("Only 8 charachters allowed, system will exit!")
            time.sleep(10) # stops compilation of code for 10 secs
            os.system('cls') # clears the terminal window
            sys.exit() # closes the terminal window

else:
    print("Your text is ",text," wait for encryption.")

A function to decrypt the text input by displaying the charachters in even positions first; then odd last.

def encryptText(): a = t1[0] # creating a var a and assigning it the first value of t1 lis b = t1[1] c = t1[2] d = t1[3] e = t1[4] f = t1[5] g = t1[6] h = t1[7] etup = (a,c,e,g,b,d,f,h) # creating a tuple(immutable one dimensional array) with the letters from the text as elements print("Your encrypted text is",''.join(etup),".") # '' stores what will separate the tuple charachters and .join() is used to print the tuple as a string. pass

A function to revert encryption

def decryptText(): a = t1[0] # creating a var a and assigning it the first value of t1 list b = t1[1] c = t1[2] d = t1[3] e = t1[4] f = t1[5] g = t1[6] h = t1[7] dtup = (a,b,c,d,e,f,g,h) # creating a tuple(immutable one dimensional array) with the letters from the text as elements print("Your original text was",''.join(dtup),'.') # '' stores what will separate the tuple charachters and .join() is used to print the tuple as a string.

validateInput(input("Enter the text with 8 chars:")) # calling the function with user input text passed as a parameter t1 = list(validateInput.text) # creating a var t1 of list type from validateInput's text. Used in order to be able to manipulate individual charachters encryptText() # calling the function decryptText()

time.sleep(10) # stops compilation of code for 10 secs os.system('cls') # clears the terminal window sys.exit() # closes the terminal window
