gollark: So it's a random 4-byte string?
gollark: That actually probably *would* put it in the range of practical bruteforceability, since there are only 4 billion possible 4-byte values and anything you're doing by hand can't be *that* slow to run on a computer.
gollark: That's, er, 4 bytes.
gollark: Also also, things involving just scrambling the alphabet and using that fixed "scrambling" for each letter of the input are vulnerable to stuff like frequency analysis.
gollark: Also, the fact that it mixes up the alphabet a lot isn't exactly very relevant, since the vulnerable bit is probably how it, well, generates the "scrambling" in the first place.
