Project description
Bravo! You have received a Medical Diploma from
the Orbital Convergence University International Air and Water Embassy of the Tangerine Planet.
You are now officially certified to include this module in your practice.
nocturnal
description
Make sure you use this inside a Docker container.
It runs deletions.
obtain & build
pip install nocturnal
fernet tar
Given a directory (in the CWD) named: "constant"
This produces a key: fernet.key.JSON
Then produces encrypt: constant.tar.fernet
Then produces decrypt: constant.decrypted
These procedures search for: fernet.key.JSON
nocturnal fernet_1_tar produce_key
nocturnal fernet_1_tar encrypt --dir "constant"
nocturnal fernet_1_tar decrypt --file "constant.tar.fernet"

<h3>verification</h3>

<p>
With the "public" key, the unsigned byte string, and the
signed byted string, the "verify" procedure figures out
whether the signature is legit.
