Like all of the spam-looking stuff in the beginning of the LinkedSword. What does it all mean? How does it work?

It's a hash of the script's source.

It's a hash of the source? Why would they show a hash *and* the source? Are they asking people to reverse engineer their hashes?

The hash is there to prove that the script's source hasn't been tampered with.

The process of finding the algorithm used to hash a string, given only a string and that string hashed, is difficult.

I remember popinman found a way to circumvent the validation a while ago.

@Seranok It usually isn't, provided that they use a common hashing algorithm like sha1 or md5 (which, by the way, is extremely vulnerable to attacks and should not be used for security purposes).

More like "an editable Sword", as it won't be linked anymore.

It has a link to a Roblox Lua model.
