Encrypt string in Python

Question

I need to encrypt a small string in Python. Is it possible to use a secret key to encrypt the string? Is there a good way to do this and achieve a reasonable encryption leve

Answer 1

I would do this with the easy to use cryptocode library (https://github.com/gdavid7/cryptocode).

Encrypting and decrypting is relatively simple compared to other libraries:

## Encrypting:
>>> import cryptocode
>>> myEncryptedMessage = cryptocode.encrypt("I like trains", "password123")
>>> print(myEncryptedMessage)
M+Wykmlub0z7FhEdmA==*PvAbXRNx0SiSDHHxLsKZ5w==*ihQM/fdkgrX3G+yOItyAUQ==*QFNDmuUP1ysgo01/P2MNpg==

## Decrypting:
>>> import cryptocode
>>> myDecryptedMessage = cryptocode.decrypt("M+Wykmlub0z7FhEdmA==*PvAbXRNx0SiSDHHxLsKZ5w==*ihQM/fdkgrX3G+yOItyAUQ==*QFNDmuUP1ysgo01/P2MNpg==", "password123")
>>> print(myDecryptedMessage)
I like trains

The only large disadvantage to this library over others is that it does not have many options to change around your string compared to other cryptography libraries. But it is perfect for a lot of people who just want an abstraction, and don't need to configure custom settings.
