Reverse Engineer MD5 Hashes

[Becksbox]

Hi

Is it somehow possible to reverse engineer md5 hashes ?
Many websites store the md5 hash of the users passwords.
I mean, i just found http://md5.rednoize.com and i wondered how this site works.
It seems that this site can reverse engineer md5 hashes / passwords.

No It's strongly hard to reverse the md5 hashes ... and if it's found such a method ,the hashe will be upgraded to another version !

This site simply has a great database containing a big collection of hashes of many strings and it search in them only, not all hashes could be found in this site , try it yourself .
