sent the reward. CONGRATULATION AGAIN!

hacking is many factors. Not only technical. also social factors are very important when you see this hackathon...  Wink  and you won because you combine ALL factors you need to solve a hackathon. GOOD JOB!


lol, came back online for another round and gone! Smiley
Congratz to injust Cheesy

Can someone share the lvl5 answer? (leave lvl 6 in suspense Wink)

SOLUTION:

lvl1: "   " (3 x space)
lvl2: 15a755ba37adfc28bc6795b524071618d71096dc6a6b5df091f0947dcc74e0b0 = gost(true)
lvl3: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa  = pubkey(genesisblock)
lvl4: 8513c69d070a008df008aef8624ed24afc81b170d242faf5fafe853d4fe9bf8aa7badfb0fd045d7 b350b19fbf8ef6b2a51f17a07a1f6819abc9ba5ce43324244 = whirlpool(1)
lvl5: you must change your http-referer. i.e. "curl --referer" or addons for firefox, chrome, etc. (i.e. ModifyHeaders, and my other plugins can make this). so you change referer and make it: 'https://www.nsa.gov' - then you are in lvl6 page.
lvl6: in level 6 you get this string: ad4cd704d846b46dec9f8fb4d8c92ed4333 = md5(cryptoanarchist)+'333' = cryptoanarchist333


thank you all for join the hackathon! hope it was lot of fun! see you next weekend!
