PyNacl VS Paramiko

In my experience, using the pgcrypto module is a little clunky - it's often better for the application to be responsible for encryption and decryption (using something like Fernet or libsodium bindings) and writing into a bytea column.

Finally I managed to replace the slow pure-Python reference implementation of Ed25519 cryptography with pynacl which is a binding to libsodium, the industry standard lightning-fast C library.

It actually looks like the device is using auth type “none”. And looks like paramiko might not support password-less authentication https://github.com/paramiko/paramiko/issues/1437.

I don't use python, but it looks like this paramiko library is your answer. There's a demo server listed that can answer connection requests and handle I/O for the connection without having a shell session as an intermediary.

For the purposes of this post, let's say we are using the paramiko SSH package, and we to get a better understanding of how it works. Let's go!
