python text encryption code example

Example 1: 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 2: 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))

Example 3: how to encrypt and decrypt strings python

from cryptography.fernet import Fernet

def load_key():
    """
    Load the previously generated key
    """
    return open("secret.key", "rb").read()

def decrypt_message(encrypted_message):
    """
    Decrypts an encrypted message
    """
    key = load_key()
    f = Fernet(key)
    decrypted_message = f.decrypt(encrypted_message)

    print(decrypted_message.decode())

if __name__ == "__main__":
    decrypt_message(b'gAAAAABesCUIAcM8M-_Ik_-I1-JD0AzLZU8A8-AJITYCp9Mc33JaHMnYmRedtwC8LLcYk9zpTqYSaDaqFUgfz-tcHZ2TQjAgKKnIWJ2ae9GDoea6tw8XeJ4=')

Example 4: how to encrypt and decrypt strings python

from cryptography.fernet import Fernet

def generate_key():
    """
    Generates a key and save it into a file
    """
    key = Fernet.generate_key()
    with open("secret.key", "wb") as key_file:
        key_file.write(key)
