No way to really do that. That's kind of the point of MD5 hashing. No reverse engineering.

You only choice is to generate a MD5 hash for all your files and see which one gives you the hash you're looking for.

I have only one file , so I need something to generate hashes for all posible numbers

Most password crackers can do that, but depending on the length of the number or whether it is just a number or also contains letters, etc, it'll take you years to do it (if it's just a few numbers, it'll take you seconds instead).

Just google MD5 cracker or MD5 decrypter, or something similar, and you should get tons of possibilities.

Start by trying this online service:

It'll just compare your hash to a huge online database, so if your source is already in their database, it'll be quick.

But check your hash here:

- pretty sure it's not an MD5 hash.

my source can't be in their database because its a float numbers from file

Okay I'm a bit confused about your explanation. Is the hash for the entire image or just for one of the pixels? If it's just for one, can't you generate the hash for all the pixels and see which one fits?

if I had brute force attack software I would wait until it find the correct number
but again type of a hash in unknown still
