Reverse MD5

[phreak]

Anyone happen to know how to reverse a string that has been used by the md5 function, back to the original string?

MD5 is not reversable. (and what would be the point of using it if it was reversable?)

A forum, a FAQ, email notification, what else do you need?

Man, this is the second guy to ask about this tonight.

for all the juicy details on getting anything out of an MD5 🙂

Hi,

The only way at the moment is to brute force the hash.
That means to calculate all the possible combinations of bytes, and MD5 them. If the hash matches, you've found what you've been looking for.
But that takes a lot of time, let's say at the capacity of today's machines some 10000 years.
That means nearly impossible.

So don't try to make it.
