How do I encrypt and decrypt a string in python?

Question

I have been looking for sometime on how to encrypt and decrypt a string. But most of it is in 2.7 and anything that is using 3.2 is not letting me print it or add it to a string.

So what I'm trying to do is the following:

mystring = "Hello stackoverflow!" encoded = encode(mystring,"password") print(encoded) 

jgAKLJK34t3g (a bunch of random letters)

decoded = decode(encoded,"password") print(decoded) 

Hello stackoverflow!

Is there anyway of doing this, using python 3.X and when the string is encoded it's still a string, not any other variable type.

I had troubles compiling all the most commonly mentioned cryptography libraries on my Windows 7 system and for Python 3.5.

This is the solution that finally worked for me.

from cryptography.fernet import Fernet key = Fernet.generate_key() #this is your "password" cipher_suite = Fernet(key) encoded_text = cipher_suite.encrypt(b"Hello stackoverflow!") decoded_text = cipher_suite.decrypt(encoded_text)
