Cryptography refers to the activity of making codes and uncoding codes, though according to your context, you might be (ethically as well as demonstrably) thinking of different things when you hear the term. Sometimes these codes are made as a plot device, such as in Futurama with Alienese, in Star Wars with Aurebesh, or Gravity Falls with some of the symbols, and sometimes they're not made for the characters or the audience of a work of media but people outside that media. Sometimes the codes are simple, sometimes they're fairly elaborate in one way or another, and sometimes they're super complex. Sometimes they're designed to be hard to crack at the cost of standing out like a sore thumb, and sometimes they're made to blend in to the environment at the cost of being easy to crack (or if you're lucky, you might make or find one that can do both). Sometimes they're made to bridge communication between groups that cannot communicate under their own normal circumstances and unite people, while other times they're made to divide people by providing a veil of secrecy. Sometimes what they convey might be ordinary language or what they convey might be something entirely different. Sometimes they can be recorded and other times they might be wholly oral. And sometimes an example of cryptography might exist because all the pieces of a "code" are the way they are because they objectively make the most sense (which would make it less "cryptography" according to some and just what native inferrence calls for), while other times it could be anything as opposed to anything else, unless consistency towards another code tempts it to be a certain way.
What is your favorite, most fascinating, and/or most notable experience with existing examples of these, do your artworks, writings, or your modus operandi have or operate by any secret codes (be it any made to be found by the viewer or more for an in-universe element), and what's your ethical take on them? Discuss cryptography.
