Get access to password-protected PDF files quickly and efficiently! Instantly unlock restricted PDF documents by removing printing, editing and copying restrictions! Advanced PDF Password Recovery recovers or instantly removes passwords protecting or locking PDF documents created with all versions of Adobe Acrobat or any other PDF application. Remove annoying restrictions from PDF files! Advanced PDF Password Recovery instantly unlocks PDF documents that restrict you of printing, editing or copying of data to clipboard. This is by far the most common protection found in PDF files. If you can open a document without a password, but cannot print it at all or are restricted to low-quality output, or if you cannot copy data to clipboard or cannot edit the document, read no further and get Advanced PDF Password Recovery Standard edition!

What if you can’t open a PDF document at all without knowing the correct password? In that case, you’ll need the password recovery feature found in the Professional and Enterprise editions of Advanced PDF Password Recovery. The PDF format specifies two types of protection: the weak 40-bit and the strong 128-bit encryption. Advanced PDF Password Recovery guarantees the recovery of 40-bit keys by attacking the encryption key instead of attempting to guess the password. While the Professional edition takes up to several days to recover a PDF document protected with a 40-bit key, the Enterprise edition can unlock an encrypted PDF in a matter of minutes!

The unique Thunder Tables™ technology developed by ElcomSoft uses pre-computed tables to significantly speed up the recovery of 40-bit keys. The technology is available in the Enterprise edition, and will unlock a protected document in a matter of minutes instead of days. If the PDF is protected with a strong 128-bit or 256-bit key, Advanced PDF Password Recovery performs a range of attacks on the PDF file document in order to obtain the original password. But even then you’re not left without options!

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. The program is also able to convert Kinko's Document Format (KDF) files to PDF files (without any protection).

Three versions (editions) are available: Standard, Professional and Enterprise.

Standard: basic edition of the program, that is only able to remove restrictions (from printing, selecting text and graphics and copying them into the Clipboard, adding/changing annotations and form fields). Does not handle PDF files with "open" password set, if that password is not known.

Professional: this edition has all functionality of the Standard one, but also allows to search for "owner" and "user" passwords with brute-force and dictionary attacks, effectively optimized for speed. In addition, it has the "Key search attack", which guarantees the decryption (regardless the password length and complexity) of PDF files that use 40-bit encryption. This attack takes from a few days (on modern dual-core systems) up to two weeks (on slow computers).

Enteprise: based on Professional edition, this one has an improved "Key search attack" using state-of-the-art "time-memory trade-off" technology, allowing to break "user" password (for 40-bit encryption) in just a few minutes (instead of days, as in Professional edition), using special pre-computed tables on DVD, shipped with express mail.
