QUESTION

Is it possible to encrypt then decrypt data securely against a password in Python?

Asked 2018-Mar-24 at 19:28

I have some data in a python program that I'd like to encrypt before writing to a file with a password, and then read it and decrypt it before using it. I'm looking for some secure symmetric algorithm that can encrypt and decrypt against a password.

This question shows a non-secure way and suggests using libsodium. Since I'm using Python, I found pysodium. It seems to have tons of functions mapped from libsodium, but I don't know how to simply encrypt/decrypt data against password.

My problem is that it looks like all encryption algorithms use keys. I don't want to use keys. I want to only use a password. Just like what I do in the terminal:

So my question reduced to: "How can I encrypt data against a password in Python". I gave up on pysodium due to the lack of documentation. I used cryptography and argon2 packages to write my own encryption algorithm (it's not my own crypto algorithm, I know Rule No. 1 in crypto; it's just the procedure to utilize what's already there). So here are my functions:

QUESTION

Installing Python's Cryptography on Windows

Asked 2017-Nov-22 at 05:15

I've created a script on windows to connect to Remote SSH server. I have successfully installed cryptography, pynacl and finally paramiko(Took me an entire day to figure out how to successfully install them on windows).

Now that I run the script, it pops an error saying that the DLL loading has failed. The error seems to be related to libsodium but I cannot figure out exactly which DLL is to trying to load and from where. Just to be on the safer side I also installed pysodium.

Here's the script:

After a lot of googling, I finally stumbled upon this. As mentioned in the conversation I uninstalled my previous pynacl installation, downloaded the zipped source from https://github.com/lmctv/pynacl/archive/v1.2.a0.reorder.zip, downloaded libsodium from https://github.com/jedisct1/libsodium/releases/download/1.0.15/libsodium-1.0.15.tar.gz, set LIB environment variable to D:\Users\prashant-gu\Downloads\libsodium-1.0.15\bin\x64\Release\v140\dynamic, and finally installed pynacl form this downloaded source using

pip install .

Now it works fine.

During the installation of paramiko, I also happen to download OpenSSL from https://ci.cryptography.io/job/cryptography-support-jobs/job/openssl-release-1.1/, and set INCLUDE environment variable to D:\Users\prashant-gu\Downloads\openssl-1.1.0g-2015-x86_64\openssl-win64-2015\include in order to successfully install the cryptography package which happens to be a dependency for paramiko.
