You mean, given an MD5 hash, retrieve the original text?

The short answer is: you can't - that's the point of an MD5 hash.

The longer answer is that it's unknown whether it can be done in any reasonable amount of time (even with reasonable being tens of years). You could of course generate all possible text, and eventually stumble upon a text that gives the given MD5 hash, but even then it's not sure whether you got the right one.
