Hint #2: that code is SHA1. You have to find out the string that produced that hash by what ever means you see fit and you can give the correct answer

But from what I know, SHA-1 is a one way hash right? It isnt possible to decrypt it without maybe brute forcing? Because thats what the hash is meant to be - irreversible?
Is it possible to decrypt a SHA-1 hash? (Stackoverflow)Unless I'm missing something here...
