So here it is, I'm trying to break the one stupid internet game and it's giving me some pain...
Here is an exemple of the information sent to the server :
lapTime 71417
langue FR
who MINE
fbid_friend XXXXXXXXX
hash b060521884128b17b622f478fbffc2fe
rnb 0d08c8abd04f3a09fdded3b3eb830ace
mystring 13950,bdbb1a6e05b8a7868805bd237f00b71a,14250,7145048e2953f19159945705a7980ce6,15133,c7721bcb5410266c8e6d5c083d079959,14450,872c74b2902511979da3787f2e1705ba,13634,287502bbabe880233418d3f8e7a98065,
hashtime 700c79ce00a436eeca15c052e6c56ba4
i_h 25da9af83cef2118511e81c955c356f4
i_r 2612485859300
e_r 2612486002180
e_h 6cb02da732db68a50a0f39af7749d072
So... I suspect that i_h is the hash of i_r and e_h is the hash of e_r...
lapTime should be hashed in either "hash" or "hashtime" field.
I think rnb is a random number (or the hash of a random number I guess)
I had to hide the fbid_friend for privacy reasons but I don't think it's related.
The "mystring" field should be in a format like "number1,number1_hash,number2,number2_hash,etc...)
The thing is there must be salt or sth because I don't understand how they do it... But all the info should be there (not the salt if it's salted obviously...)
Can someone help me with this ? |

Without all scripts nobody can't tell you what is all this hashes. |
