A program to decrypt protected Adobe Acrobat PDF files, which have owner password set, preventing the file from editing (changing), printing, selecting text and graphics (and copying them into the Clipboard), or adding/changing annotations and form fields (in any combination); can also decrypt files protected with FileOpen and BPTE_rot13 plug-ins. Decryption is being done instantly. Decrypted file can be opened in any PDF viewer (e.g. Adobe Acrobat Reader) without any restrictions -- i.e. with edit, copy, print, annotate functions enabled. Can operate in a batch mode. The program is also able to convert Kinko's Document Format (KDF) files to PDF files.
