Kaspersky Lab spent more than two weeks trying to crack the MD5 hash using a computer that tried more than 300 billion plaintext guesses every second.
Interesting. Aren't MD5s vuln to collisions? http://www.wolframalpha.com/input/?i=%28convert+2+weeks+to+seconds%29%28300+billion%29 http://www.wolframalpha.com/input/?i=%28convert+2+weeks+to+s...
- sp332 12y agoNo. You can construct two messages with the same MD5, but only if you control both messages. Finding a message with the same MD5 as a given message, or password, is still infeasible. Even if you try 3x10^17 ~= 2^58 in two weeks, MD5 has 128 bits of entropy so you'd need 2^70 ~= 1.1x10^21 times that to exhaust the space. Wolfram Alpha says that's 3.3x10^9 times the age of the universe.
