Didn't someone make a program where if you have the plain text (i.e. the actual key) for one key.dat file, you can use that information to decrypt any other key.dat on that computer?
In addition to Trinick having made one, I made one as well in my KeyUtils program.
Yeah
Also if you have enough encrypted key.dats from another computer, you can figure them all out iirc
This is true. If you have as few as 3 keydats made on the same computer (Knowing nothing else about the keydats, not even the BLIDs), using more advanced attacks it becomes feasible to get all 3 of the keys. Having more keys reduces the workload significantly, by the time you get to 5-6 keydats you could theoretically do it by hand.
