In the end MD5 and SHA1 have been cracked because computers can't do true random numbers (they're based off algoritms like the twister) and thus reversible. so if a team of determined hackers want your password than they will get them, the only true way to be secure from network intrusion is to black box it - I find security to be more a game of "Tire out the hacker" then "Keep the hacker out" (I refrain from using "he" or "him" because some girls are very nasty hackers..)
MD5 was cracked a while ago, there are only rumors of sha1 being cracked. Sha1 nor MD5 use random algorithms because they
come out with the same result every time. They destroy the original value, meaning that even if you can reverse the process, there are unlimited possibilities of what it could be. If you dont have a short or dictionary word password, the hacker wont know one from another. Using two or more wont render much since anyone experienced enough to crack it once would catch on to what it was and just do the process again.
