We could waste our whole life and about 5 generations after and still not crack them till they find out how to truly break them lol. _________________ Shai-tan ?In short: just say NO TO DRUGS, and maybe you won?t end up like the Hurd people.? -- Linus Torvalds Re: defeating crypt() funtions Posted: Tue Apr 12, 2005 12:17 pm waraxe Site admin Joined: May 11, 2004 Posts: 2407 Location: Estonia, Tartu y3dips wrote: waraxe : is there a way to defeating crypt function ? for you all who dont know about crypt() , please read this http://docs.php.net/en/function.crypt.html What do you mean by "defeat"? If Crypy() function will make oneway hashes, then as always there are possibilities to attack by wordlist and just bruteforce. And because Crypt() function by default uses 56bit DES, then i dont think, that it's very secure hashing Posted: Tue Apr 12, 2005 3:08 pm y3dips Valuable expert Joined: Feb 25, 2005 Posts: 281 Location: Indonesia thats why i use "defeating" not "breaking" coz i dont want to use some brute forcing ( .. it spend more time, even using some word list, i know its hard to reverse it back. here the story , i found some CMS using this to encrypt the password ,n i found the hole n could get the crypted password, now i just try to known the plain password. i try to use reverse technique , but it useless coz the function get to variable and output one variable (in hash) for example Code: $passwd = $user.$pass; $hashed = crypt($passwd); but what i get was the "hashed" btw thanks all ; maybe i should release it (advisories) without the way breaking the password _________________ IO::y3dips->new(http://clog.ammar.web.id); Posted: Tue Apr 12, 2005 3:46 pm erg0t Valuable expert Joined: Apr 08, 2005 Posts: 55 Location: Uruguay The metods to encrypt passwords aren?t the same as used to encrypt data. As waraxe says, the encryption is one way, is more like a cheksum. You can?t go back. The only solution is brute force. I think the best solution to "defeat" this kind of encription algoritms is to try to create the most optimized version of the algoritm to win procesing time when bruteforcing. In some cases you can use something like rainbow tables but, in others (when the hash depends of the user name and other parameters too) you need bruteforce. Posted: Tue Apr 12, 2005 3:59 pm y3dips Valuable expert Joined: Feb 25, 2005 Posts: 281 Location: Indonesia im agree with you (erg0t) also with waraxe, im just curios about it. i know it was one way hash n no way to roll it back , so we could do some brute forcing also im agree with finding best algorithm to speed up the brute time . but i just want to know if there is one of u find the same problem, n ive just wondering if the vendor has use the wrong method in authenticate (for example : send the crypted password as a variable to be matched with passwd in database/file ) btw , thanks for all the responses _________________ IO::y3dips->new(http://clog.ammar.web.id); Posted: Wed Apr 13, 2005 3:45 am shai-tan Valuable expert Joined: Feb 22, 2005 Posts: 477 wow so my post was quite relevant.....
