Still here? Well, letting time be wasted should we not do then. People say that sometimes less is more, but how much is enough of that less? Let's see if you can get something out of this:

If you are stuck, that's fine. It's OK to rest sometimes and take a look at where we came from. Anyway, what does resting mean to you? I usually watch some horror movies, for example, picking one from the early 2000s. As many great ones were made then as not-so-great ones, so there are options to choose from. And what triggers your fear? Are you afraid of ghosts?

If you are stuck, don't give up, just have a rest. Here, have a nice vignette for your phone

Well this is actually a real cryptography problem. If you want to encode something short, no matter how long the key is, only a part of it will be used as there are no input characters to work with, and the encrypted text would be weaker than you think. But if the roles are swapped and the secret text is being used as a key to encrypt something longer, it will be much harder to break.
So basically what you see here is the result of such an encryption, and you need to find the key. What you need is the text that was encoded (something without spaces) and the cryptography method.
As you see, the encrypted text has letters and numbers in it, so you might need to alter the alphabet.
Hope I have given enough clues.
