Advanced PDF Password Recovery (APDFPR) unlocks Adobe Acrobat PDF documents and instantly removes restrictions on editing, printing and copying. The patented Thunder Tables(tm) technology guarantees the recovery of 40-bit keys in under a minute. GPU acceleration is available for the latest 256-bit encryption.

We offer a variety of editions to satisfy the most demanding customer yet affordable to casual users.

The Standard edition is a perfect choice if you have a restricted PDF file that deprives you of getting a hard copy and/or disallows editing and copying of data to clipboard. The Standard edition instantly removes all restrictions and unlocks the protected PDF file.

If you cannot open a PDF file without knowing the password, you need the Professional edition. This edition comes with everything included in the Standard version, and allows retrieving the "owner" and "user" passwords with brute-force and dictionary attacks. The unique Key Search Attack guarantees the recovery of PDF documents protected with 40-bit encryption. Accelerated by GPU and effectively optimized for speed, this attack can recover the protected documents in a matter of days when used on a modern multi-core PC. Removing JScript code, form fields and digital signatures is also an option.

The Enterprise edition extends the features of the Professional version by adding the unique, patent-pending Thunder Tables technology that allows recovering “user” passwords in a minute’s time frame instead of days. The Thunder Tables technology uses pre-computed data and supports 40-bit encryption only.
