A brute force attack on a MD5 hashes seems to be useless, considering the following facts:
- there are 2^128 of different MD5 hashes. (16^32)
- there is an almost infinite number of possible character combinations
- if you create 2^128+1 different strings, MD5 will produce at least 2 equal MD5 hashes.
- if equal keys are possible it seems to be (?) impossible to "encrypt" an MD5 hash
