Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
much thanks to @gary_host_laptop for the logo design :)
This is for pedagogical purposes. Please do not cypher actually important messages with this.
Anyway I think it can bring with little ones, and adults alike, interesting conversations around :
... and a lot more!
Is this quantum-resistant?
Doubt I can do a PR to https://github.com/open-quantum-safe/ with that yet... but that does beg the question, what other schemes could be represented tangibly without complex mechanisms?
It's water-resistant.
good enough.
Caesar liked this post.
This is meant for simple replacement algorithms like ROT1, ROT13 etc. right?
Actually no I use it for CRYSTALS-Kyber /s
Yes, just joking it's not even meant for a "replacement" but rather how to give a pragmatic affordable (the 1st one I made was literally just 2 paper strips and scotch tape) fun way to explore ROT... but IMHO it can be just a starting point. You can do that and sequence them, e.g. ROT-X where X is the date so e.g. today is 06 12 2025 so you would ROT0 the first letter, ROT6 the second, etc.
It is only meant to be fun, please don't use this in actual serious situations.
FWIW changing ROT is https://en.wikipedia.org/wiki/Vigen%C3%A8re_cipher as @drspod@lemmy.ml pointed out, I already learned something!
It's a Caesar cipher
It could also be a Vignere cipher
You're a vinegar cipher
thanks, unlucky Rich
More specifically, the bracelets are lined up for rot13.
It might be more fun to print two randomly ordered bracelets that need to be lined up correctly to en/decipher a message.
That would make sense, if it's educational then it's probably used to teach about the Caesar/shift cipher
. . . puns like:
