Public-key encryption Dec 30, 2019 · As it turns out, encryption is a big part of what makes password systems work. In general, most systems will encrypt the password that you type in, and just keep the ciphertext. The next time you log in, it will encrypt whatever you’ve typed in, and then see if that matches with the ciphertext on file. If it doesn’t, you can’t log in. I've not looked at every file in the repo yet but a couple of suggestions so far: Look at using the PyNaCl library. It abstracts away a lot of complexity and uses modern crypto. In your current design, the server is decrypting then re-encrypting any messages. This means that the messages are visible as plain text for a short duration on the server.
