Can someone crack this hash for me?

Both MD4 and MD5 are one-way hash functions. What this means is not just that it is extremely expensive to find the original string but rather that even once you find the original string you can’t be sure you have done it correctly

This is because you can hash an input of any size and it will always return an output of 128 bits (or 32 hexadecimal characters). You can put in an 8 character password or a 20GB database file and the hash will always be 32 hexadecimal characters. It should be clear to see from this that there are many, many different input files that will cause the same hash string to be output. I have linked an example of two different inputs that create the same output in the sources.

If you don’t know something about the input already that will help identify it then you can’t ever crack an MD5 or MD4 (or SHA1 or any of that family) hash. Brute forcing hashes usually involves going through all possible inputs and hashing them to see if they produce the correct output. Anything you can do to reduce the number of possible inputs will make this faster.

Incidentally, it usually doesn’t make any difference if someone types in your actual password or a completely different password that produces the same MD5 hash because good websites don’t know your password. They only know the hash. If you have a password longer than 16 characters then there’s a very good chance that a shorter password will also get you in to the same website. For this reason and many others, websites should not use MD5 to store passwords.

I tried your hash in Google and at a couple of the reverse MD5 lookup websites available (linked in sources) and none of them had your hash. This suggests that it is either an MD4 hash as you suspected or it is an MD5 hash that no one has ever entered into any of these databases.
