Cisdem PDF Password Remover Software Review
Cisdem PDF password remover is one of the best pdf password recovery software for mac. Cisdem did a great job in making the software as simple as possible. When it comes to functionality of the app, the recovery speeds are quite not promising on my mac mini although more powerful computers such as an iMac would have way better speeds. I was able to get over 14,000 passwords per second speed which is not that bad when considering the limited resources on my mac mini.
However, the lack of dictionary attack was quite depressing for me. It took me over a day to unlock a PDF with password “test123”, whereas the same when tried on Advanced PDF password recovery software, took only a few seconds to unlock. That’s the power of dictionary + brute force attack instead of plain brute force. I hope Cisdem will roll out dictionary attack feature in the future. Moreover, the lack of a progress bar was also quite bad.
