Hi,
Then there is also "PDF Unlocker", this software is able to remove encryption passwords from 40 to 128-bit. It is a free utility that will also allow you to unlock protected PDF files. The same principal applies, you drag and drop the file into the software and you are then able to print, copy or even edit it. With this software you are also able to convert EPS, and Photoshop into PNG bitmap, and the best thing about this software is the fact that it is completely free of charge.
