Partial recovery

[aprizm]

I do have some understanding of how sha1 encryption works. That is exactly why I dont get how they come up with these partial results. Changing 1 character would theorically change the whole hash but somehow if I copy half the hash x2 and send it as a hash in CrackStation it still gives me the partial. So it is able to get partial results from half a sha1 hash somehow. I really want to understand how they do this Ive pm the author of the siite. This could be very useful in cracking those last hash.
