Source Code are bellow:
from cryptography.fernet import Fernet
key = Fernet.generate_key()
with open('mykey.key', 'wb') as key_file:
key_file.write(key)
with open('mykey.key', 'rb') as key_file:
key = key_file.read()
fernet = Fernet(key)
with open('myfile.txt', 'rb') as file:
original = file.read()
encrypted = fernet.encrypt(original)
with open('myfile.encrypted', 'wb') as encrypted_file:
encrypted_file.write(encrypted)
print("File encrypted successfully.")
Copy that and save to this name: encrypt.py
