Yo, I was looking for something like this and Hellextractor is looking awesome!
Took a look to see if we can get the preimage from murmurhash (from what I gathered by reading this thread this is the hash function that Stingray uses, correct me if I'm wrong) and it seems like it may be possible?

Murmurhash in the post is not quite the same as the one in Hellextractor but some of the lines do seem to match up.
