# Need help with an online puzzle / riddle

I found this online riddle at m4tr1x.ws, but now I am stuck. It seems you need to gain deeper and deeper access to this virtual Matrix-style computer system. First you need to create an account via the register command. That is easy, after confirming via email you can login to the system.

Afterwards you need to connect to the site via a Tor browser. It turned out the address to connect via Tor is "matrix4ozv2gicar.onion". Connected via Tor you can login again with your user and issue the command redpill tor.

Now you gained level 2 of this riddle. Writing just redpill now gives you the following:

bruteforce SHA224: f6d54a854ca1d0e987b798e1593de79631b8f2329fb84a15725bf9b2


And here I am stuck. I have no idea how to decrypt that string. Does one really have to brute-force it? That doesn't feel like the real answer to that problem. I tried several Matrix-related phrases and words, but without success.

Any ideas?

• I have fed every word in a bunch of electronic wordlists, and in some text I fetched from the web some time ago for a word-analysing project, into Python's hashlib.sha224 function, with various different capitalizations, and nothing has come back with the hash value given here. – Gareth McCaughan Jul 16 '19 at 13:52
• I suspect that further progress may depend on details within this super-sketchy-sounding game, which I for one am not going to go anywhere near :-). Puzzles here need to be self-contained, and it's beginning to look to me as if this one effectively isn't... – Gareth McCaughan Jul 16 '19 at 13:54

• I would be careful - this could be a hacker way to get to you. – Moti Jul 16 '19 at 15:26
• @Adam Also closed there as off-topic -- which it is; I don't think it's obviously off-topic here, unless there's a real dependence on material not shown here ... which there well might be. – Gareth McCaughan Jul 16 '19 at 16:34
