python encryption code examples

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: 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))
