encryption and decryption python code example

Example 1: encrypt and decrypt python

# encrypting
from cryptography.fernet import Fernet
message = "my deep dark secret".encode()

f = Fernet(key)
encrypted = f.encrypt(message)
# decrypting
from cryptography.fernet import Fernet
encrypted = b"...encrypted bytes..."

f = Fernet(key)
decrypted = f.decrypt(encrypted)

Example 2: encryption using python

#Made by myself

import random

text = input ( "Enter text: " )

result = ""
private_key = ""

for i in text:

    rand = random.randint ( 1, 125 )
    en = rand + ord ( i )
    en = chr ( en )
    en = str ( en )

    private_key = private_key + str ( rand ) + " "

    result = result + en

print ( "\nPublic key:", result )
print ( "Private key:", private_key )

Example 3: how to encrypt text in python

text = input()

def encrypt(t):
    chars = list(text)
    allowed_characters = list(" abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789,.?!")

    for char in chars:
        for i in allowed_characters:
            if char == i:
                chars[chars.index(char)] = allowed_characters.index(i)
    return chars

print(encrypt(text))
