    Well, a company I'm working for has ~25 spare dedicated servers and I'd like to to take a try at distributed brute forcing; is there any methods to check if a block of decrypted data is valid or not?

    What I've been doing is trying to unpack the file from its [Only registered and activated users can see links. ]. Verifying that it's actually a container (by checking the header and trying to decompress it) has worked so far for me.

    Brute-forcing isn't feasible, as demonstrated by several people (2^128 possible values, remember).

    Decompress the container after decryption or you can check the GZip or BZip2 header keys which is a MUCH faster way of doing it. However there's a 1-65,536 chance in getting the correct header keys for a GZip file and still have the incorrect XTEA key. For BZip2 encrypted files it's a 1-4,294,967,296 chance of getting the correct header but incorrect XTEA key.

    im still wondering why your all bothering your ass with this, someone from rsbot (apparently) released like 80% of the mapdata, decrypt all possible maps using that, then SAVE THEM unencrypted, then if your still not happy go find the ones that you want, get the XTEA keys, dump the map then add that to your collection of maps, once you have 90% of maps done your pretty much done, make it publicly accessible and then just repack each (revision we decide to create) cache with the unencrypted maps....

    like you all must be a bunch of retards if your trying to do the hardest way possible to get things done, (THAT PEOPLE DON'T EVEN WANT DONE????????)

    We can still bruteforce mapdata for older revisions that rsbot didn't release to us

    Apart from the fact we can't because it takes too long

    Even though bruteforcing isn't feasible, you might want to validate the map files for other reasons...
