It works for some input which takes it around 14s to crack but refuses to work with other inputs. i've revised it several times but my only conclusion would be, the input is faulty, which is hard to believe. thats why i'm askin for your help...can some1 who finished the mission in JAVA (or any1 who understands JAVA) PM me, n i give them my code. i'll even send u a sample of input that refused to work!
my method was bruteforcing the serials and in the process creating the md5password as well....PLZ help me!!!!
PS: For those who r wondering why im bothering with it n yt i've finished it, well, dats jus how i am ! and anyone who doesn't bliv i've completed the mission, check my profile http://www.hackthissite.org/user/view/jpmut/.
[Edit]:Don't PM me, apparently my PM is locked don't know why, but i'll ask in another post..well, my email is jpmutanguha@hotmail/yahoo.com...write to whichever email u want!
[Edit]: u can PM now, its been unlocked!
I am having somewhat of a tough time completing this programming 3 challenge. My first impression was that since the time limit is as long as 120 seconds, it's probably going to need bruteforcing or a dictionary attack, and looking at the encryption algorithm seemed to support that. So I made a little C program to cruch through some dictionaries (you can download it here [Link Removed]) then tested it on some text encrypted with the original php function. It worked for the test, but even after 80,000,000 lines of dictionary files of digits only, uppercase only, lowercase only, and even this monster one called the argon list, it isn't finding a valid password for the numbers encrypted on the website.
Any pointers? Should I be looking for a way besides bruteforce on this one? Or is my program just slow and I should optimize it more? Any advice is appreciated. Thanks in advance.
