can you post the solution? now the wallet its empty so we can check it

LEVEL 1: the secret code is hided in the second JS-function. You MUST SCROLL DOWN.
LEVEL 2: The URL passes variable to PHP. You must change the variable "68934a3e9455fa72420237eb05902327" which is md5("false") and make it md5("true") = "b326b5062b2f0e69046810717534cb09". in example: http://www.md5-hash.com/md5-text-encrypt
LEVEL3: "" is hided in sourcecode. This is URL encoded string. You make the url-decoding: http://meyerweb.com/eric/tools/dencoder/ and it give you: "goodjob"

LEVEL 4: this is again a md5 hash of the value true. 1 can also be true. so md5(1) = "c4ca4238a0b923820dcc509a6f75849b"

LEVEL 5: The key is hided IN the photo. You open the photo in ANY texteditor or with cat/nano/vi/vim and you see on the end of the file:
"5OEDrG8yU1ortreRJXeyVed24BDOatCGvok8PQDthB9M5wVBvChn". so we now from level 1 the hint ROT5. This mean ROT5(originalkey) ="5OEDrG8yU1ortreRJXeyVed24BDOatCGvok8PQDthB9M5wVBvCh". the "n" is one character too much because private keys associated with uncompressed public keys are 51 characters and always start with the number 5 on mainnet.
so you only do it reverse ROT26-ROT5 = ROT21: i.e with: http://planetcalc.com/1434/ and you get real privkey: "5JZYmB8tP1jmomzMESztQzy24WYJvoXBqjf8KLYocW9H5rQWqXc"

it had been very easy Grin

asterix's and Obelix's biggest enemy was roman empire, caesar. they used rot algorithms to encrypt important messages. so the key must be decode with rot algorithm. anyway, i tried all variants of it, but the key was always wrong.

Work on the hint I gave. (above post)

Seefur = Cipher.

Find the rest of it. It is quite simple. You already have rot5 that is quite enough Wink

So... I found the key

Tried to decode it in many different ways and nothing worked, can you give any hint on the "translation" of the key?

Can you give me some clue about the final part ? Asterix and Obelix what relevance ? and if the answer will be rot5 or rot47 ?

the final answer is a private key you can import in your wallet. Asterix and Obelix have a big enemey. This enemy KNOW HOW to decode the final answer. But before you can decode, you must find the key. And aster/obelix HAVE the key.....
