PDFKey Pro 4.1.0
Unsophisticated utility that can quickly unlock PDF files
The PDFKey Pro user interface is represented by a single window that contains an unlock and a lock icon: simply drag and drop the document you want to process on top of the appropriate area. Keep in mind that PDFKey Pro is intended to help you when you forgot your document’s passkey, and will not function with DRM protected ebooks.
When unlocking a file, the application will create a copy of the original document, without including the password protection: the original file will not be altered in any way. By default, the output file will be placed in the source folder, but you can easily change that via the Preferences window.
Lock your own PDF documents and use different encryption methods
At the same time, if you choose to lock a document, you can set up two passkeys: one for opening the file, and one for printing and copying. In the first case, you can choose between 3 encryption algorithms: RC4 40bit (Adobe Acrobat 3 or later), RC4 128bit (Adobe Acrobat 5 or later), or AES 256bit (Adobe Acrobat X or later).
Moreover, you can decide to allow printing and copying certain parts of the PDF document even without a password. To help you differentiate between the different versions of your documents, PDFKey Pro will add “locked” or “unlocked” suffixes to the output files accordingly.
Powerful PDF processing utility that can batch lock or unlock documents
PDFKey Pro is a great tool to have around if you want to make your PDFs editable or printable even if you do not remember the protection passwords. In addition, PDFKey Pro can be used to lock your own PDF documents for safe transfer. Since the app comes with batch processing capabilities, you get to deal with large PDF documents collections in no time.
