Task 2 Note:
A good SHA-512 Base64 hash tool that is savable as offline as an extra security step is here:
https://emn178.github.io/online-tools/sha512.html

The first step would be to cop & paste the text beginning "CONTAINERIZATION" and ending "...35c02b60". The TweetNaCl uses a rare encoding base for their hashes, so this is using Base64 as an easier way to achieve consensus.
