Recently, GPU computing power is being deployed, aiming to increase the computing power to 5-6 times that of before. More GPU computing power will help recover password clues that could not be exhaustively searched before, such as masks longer than 10 days, which were previously not calculated due to the long duration, unless all other password patterns had been tried. Now, it only takes 1-2 days to compute, making it easier to achieve results. Of course, the costs involved are also considerable.
