Question

Python: Using chr() and ord() write a function called en_crypt() that takes into input a string and returns a new encrypted version of the input string. Example: "atwOta@0202" should return "fy|TyfE5757", then write a function de_crypt() so that "fy|TyfE5757" returns "atwOta@0202"

Answer 1

def en_crypt(s):
    result = ''
    for ch in s:
        result += chr(ord(ch) + 5)
    return result


def de_crypt(s):
    result = ''
    for ch in s:
        result += chr(ord(ch) - 5)
    return result


enc = en_crypt('atwOta@0202')
print(enc)
print(de_crypt(enc))
