Post by: 0x0010 on December 18, 2016, 11:21:37 AM
No money prize for now, but you can choose from:

- Netflix account.
- Spotify account.
- DirecTV
- Pandora
- Bascially anything.

This should be for fun though :)



Okay, so here's your first HINT.

- Find the VALUE within.

- I guess we could figure out the base? (32*2?)

- ?action=profile;u=<>



It all begins here. Use the hints.

param= N-0



Solution will be posted in 2 hours.



If you get it before then, post or PM me your answer. Steps should be included.

With the first hint, I'd assume the next step has to do with "NTU5ODA0"

I wanted to give some extra time for people to get more of a chance but oh well. Here's the solution.



Hint 1: "Find the value WITHIN"

'NTU5ODA0' - that was WITHIN the two halfMD5 hashes.



Hint 2: "I guess we could figure out the base? (32*2)"

Should be pretty easy.
32*2= 64 -> Base64.

Find the plaintext by using a BASE64 decoder.



Hint 3: action=profile;u=<>

u=<plaintext of base64>



Final answer: https://bitcointalk.org/index.php?action=profile;u=559804

= !Donator!

(Account was chosen at random for the contest.)

Thanks to those who tried. More coming soon.
