-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Hans, Thursday, September 2, 2004, 10:44:23 PM, you wrote: HP> Actually, the http://passcracking.com site will crack MD5 hashes using HP> rainbow tables, but they are non-salted, as salted MD5 is too HP> difficult for precomputation attacks (for now). I can feed them the salted MD5, just removing the salt pre/post-fix. Imagine the password "me" and the salt "ab". In such a case, such a lookup would return "abme" as the password. I know the "ab" is the salt, so I remove it, and I have the "me" password. In other words, as long as it's not input to the hash algo in a different way, just added to the password before being sent to the hasher, these tables will be able to look them up - today. However, if there's a limit of 8 characters, then it's 8 - saltsize that becomes the new 'max size password' that those tables can look up for you. This presumes, of course, that the salt characters are part of the character set that are used for creating the tables in the first place. - -- Best regards, Marius mailto:mahuja () c2i net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) iD8DBQFBQH68l9nYJJam7WsRAjRNAKCQz32Sp6EFzI/ZaKYpS7v1kpnJEgCffv9X I1Y/NNl92bu6D+w5zvY8N4g= =Fk9n -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Ethical Hacking at the InfoSec Institute.
