This program (Advanced PDF Password Recovery, or APDFPR) is intended to decrypt
password-protected and restricted Adobe Acrobat PDF files, which have "user" password
set (required to open/view the file), and/or "owner" password (when the file is only
protected from editing, printing etc), i.e. remove the protection and/or break the
PDF password. Restricted files are being unprotected instantly, while decryption of
files with "open" password may be time-consuming.
