Is there a (weak) encryption mode using Morse code? Message -> Morse -> 0 for dot 1 for dash -> base 10 version of the number. Or hex if you're feeling frisky.
It would need a leading 1, I guess, for messages that start with a dot. And is probably not particularly efficient. But could be an interesting puzzle in a treasure hunt/escape room type thing.
@dconley Well, why no use binary directly, can even be ~compatible with morse code:
0 -
1 .
@lanodan_wtch for obfuscation, I guess. And also because I didn't think it through too much! I'm reading about digital transmission protocols over radio waves and thought that could be a simple implementation. Yours is much simpler 😆
@dconley Also for the algorithms I think you can use thoses used in OTR or smssecure/silence. (axolotl I think)
