Was just documenting the KittenMoji standard I use to Base256 encode your ed25519 secret key in Kitten.
The full alphabet:

@aral you encode secret keys with emojis? is that allowed‽‽‽
Aral Balkan
@blogdiva Last I checked, I didn’t have to ask anyone for permission ;)
Aral Balkan
@jalict Why not? :)
The design decision behind it is so folks can’t write it down on a post-it or something and have to keep it in their password manager (or find out what a password manager is and get one, if they don’t already know).
Also, fun :)
:kitten: 💕

@aral Never really thought about encoding stuff in Emojis. What a fun idea :)
Now I wanna do savegames, or user-generated content for games in emojis haha.
How about QR code, but emojis.

@aral @blogdiva Encoding as emoji is funny, because the UTF8 ends up being 4x as many bytes as the original key, so 128 in this case, but because social media limits the number of characters and not the number of UTF8 bytes, it uses only 32 bytes of your character limit, less than hex or base64 would even though both of those would use less space in the database, in RAM, and on the wire.
Aral Balkan
@freakazoid @blogdiva Good point (no pun intended)… I hadn’t even considered that (I hope folks don’t share their secret keys via social media) 😬
Aral Balkan
@jalict Ah, haha, nice :)

@aral
Have this clean refresh video of the Emojis loading!
Aral Balkan
@freakazoid @blogdiva Ooh… Base3184, how delightfully evil :)
The only problem I see is byte count. I’m using only surrogate pairs. Afaik, there are less than 2,000 of those. So the codepoint size differences might be an issue.
Charles U. Farley
@aral @blogdiva Hmm. If we assume bigint math is available, we could use 3184 of the emoji and encode your public key with only 22 emoji :D
Aral Balkan
@freakazoid @blogdiva You remembered correctly: There are 3,790 in total in Unicode 16 (https://www.unicode.org/emoji/charts/emoji-counts.html) but that’s with modifiers.
Charles U. Farley
@aral @blogdiva Damn, only 2321 in total even including those that require multiple code points. I don't even remember why I thought there were more than that.
Base 921 encodes 256 bits in 26 emojis...
Charles U. Farley
@aral @blogdiva Hah, I'd missed that you said secret key. I seem to recall that was the original idea behind emoji-based codes, though they also look cool.
I ran a script over https://unicode.org/Public/emoji/16.0/emoji-sequences.txt and only got 1185 that don't require 2 codepoints, so you're right. I did test with one codepoint sequence and confirmed it only uses a single character of my Mastodon character limit, so I may still publish an implementation just for fun.
bumblefudge
@aral is this based on the emoji multibase or a different alphabet/algo? I've seen a few diff emoji bases over the years
Aral Balkan
@by_caballero Hadn’t heard of multibase (just looked it up, nice idea). This is just a basic map optimised for encoding/decoding ed25519 secret keys with a one-to-one mapping of bytes to emoji.

@aral I saw this and felt the need to write a rust crate for encoding/decoding KittenMoji: https://crates.io/crates/kittenmoji
That was a nice way to tune out all the stuff that is happening in the world right now. Also a nice way to get to know how to publish crates (with a crate that probably no one will use so it does not matter that much when I make mistakes :) )
Aral Balkan
@erinaceus Haha, nice :)
