| Shift Kitty:
Especially since a lot of those variables are never actually being changed, just initially set. |
| QuadStorm:
How convenient that someone made this since I very recently thought about sha1 getting phased out from https or something...anyways I'm curious to see the practical uses of cryptography in Blockland since the only time I've seen sha1 used was for a variable saving system in one of theblackparrot's gamemodes iirc that sha1'd the blid for file names. |

im confused. what exactly is this i don't speak smart so the wikipedia page doesn't help either |

But it's still deterministic (meaning the same input gives the same output), so it's reliable. The entire point is that you can't just take the output of sha256 and reverse it back into its input, that it's hard to find two inputs that give the same output, and that it's hard to find an input that matches any given output. |
