hello /wsr/ a friend of mine sent me any cryptic message I'm

typo

I was supposed to say decrypt

That's just a hash, dude.

If it's not googleable, then its only use is to show you later that he knew a particular bit of text at the time he sent you the hash.

In the renaissance, they used to do that with anagrams. Say you'd discovered something interesting, like the theory of gravity. And you were wanting to write a book about it and publish the book. But if someone came along whilst you were writing it and stole your idea or discovered it after you but published first, you'd want a way you could show everyone that you knew the idea all along before him, but you were keeping it to yourself.

So you'd come up with a sentence like

>I firmly believe that mass indubitably attracts other mass

Then you'd scramble it

>aaaaabbcdeeeefhiiiii.......vyy

And publish that. It's not practical to work out the original sentence from the scrambled one, but if someone does beat you to publication, you can publish the original sentence, and everyone can see that the original sentence can be scrambled into the scrambled sentence you published ages ago.

What your friend has done is the same as that, but with a cryptographic hash function instead of just scrambling letters by hand.

Ok thank you
