The program below uses the cryptocode library to encrypt a string in Python: import cryptocode str_encoded = cryptocode.encrypt("I am okay", "wow") # And then to decode it: str_decoded = cryptocode.decrypt(str_encoded, "wow") print(str_decoded) Output: I am okay The first parameter...
That's, indeed, the same message. f.decrypt() method decrypts a Fernet token. This will return the original plaintext as the result when it's successfully decrypted. Otherwise, it'll raise an exception. Learn also: How to Encrypt and Decrypt PDF Files in Python. File Encryption Now you...
