Fernet is an implementation of symmetric encryption and guarantees that an encrypted message cannot be manipulated or read without the key.
For generating the key, we can use the generate_key() method from the Fernet interface.
You can find the following code in the encrypt_decrypt.py file inside the cryptography folder:
from cryptography.fernet import Fernetkey = Fernet.generate_key()cipher_suite = Fernet(key)print("Key "+str(cipher_suite))message = "Secret message"cipher_text = cipher_suite.encrypt(message)plain_text = cipher_suite.decrypt(cipher_text)print("\n\nCipher text: "+cipher_text)print("\n\nPlain text: "+plain_text)
This is the output of the previous script:
