Why use simple letters, if you can use chemical symbols?

This shitpost took way too much effort...
Erinaceuserinaceus@chaos.socialOct 25, 2026, 10:26 AM@Error Nice :)
If I wasn't so hyperfixated on something else right now, I would rewrite-it-in-rust™ ( already did so with kittenmoji (https://crates.io/crates/kittenmoji).Though if you really want to analyse your data for radioactivity, you probably also have to take isotopes into account :)

63But BASF64 requires a 64 element long alphabet.

Oct 26, 2026, 12:41 PM@Error Euh, I know this is a shit post but I encountered some issues.
Decoding an empty string crashes the code.
Decoding a string without the expected padding crashes the code.
Decoding starts each decoded triplet with a null byte. So "hello\n" encoded and decoded gives "\0hel\0lo\n"- errorError@chaos.socialOct 26, 2026, 4:47 PM
@Kroppeb it's just a shitpost, I didn't do much testing; feel free to send a PR, but be aware that I don't intend to really maintain this
