Parallel Password Recovery (PDF module) v 3.0
PDF documents can be password protected for opening, using 40, 128 or 256-bit cryptography. 40-bit keys can be broken with guarantee, regardless of password used. To recover PDF open password if 128 or 256-bit keys are used, Parallel Password Recovery for PDF is designed especially to gain maximal recovery rate.
Now with Unicode and x64 support!
Features and benefitsLocal and Distributed versions
There are two key versions: local version which can be used by home user as well and distributed version for LAN and Internet. Local version can take advantage of home PCs up to 4 processors/cores. Distributed version is more professional one with possibility of unlimited clients connections.Password Definition Language
It is the most important innovative feature of Parallel Password Recovery suite. It supports all well-known standard attacks (such as brute force, dictionary, misspelled password recovery etc) and also allows users to make their own attack types. PDL language is extremely efficient if user remembers any information about a forgotten password (for example, the password consists of two words separated by a special sign or has some digits at the end).Parallel computing
Any version efficiently vectorizes a password recovery process as on physical processors/cores so on distributed workstations. Any of PDL rules are easily vectorized.The fastest PDF password recovery
The sofware is optimized for latest processors, especially for new Core i5/i7 and Ryzen architectureUses the GPU power
Supports most of modern GPU cards using OpenCL technology, including last NVIDIA Pascal and AMD RX architecture. GPU processing could increase password recovery rate in 10-20 times using one GPU!All PDF versions support
Parallel PDF Password Recovery supports all PDF versions up to latest PDF 2.0 (Acrobat X, XI, DC) files, including AES encryption, Unicode passwords, compressed files and unencrypted metadata
Unique featuresWorld's first software with GPU acceleration to recover PDF 128-bit open passwords World's first software to use OpenCL for recovering Acrobat X open passwords Support of newest x64 instructions: AVX, XOP, AES-NI, AVX2, SHA extensions Any European language passwords are fully supported using Unicode symbols

I got the error message when starting the software: "The application has failed to start because the application configuration is incorrect" or
"The code execution cannot proceed because *.dll was not found"
Try to install Microsoft Visual C++ 2017 Redistributable Package
I got the error message: "Client declines test file (This document has no user password)" or
"Client declines test file (This document uses 40-bit encryption")
This means your file can be decrypted with guarantee (instantly or in a 2-3 days). Please take a look at PDF guaranteed password recovery
- 3. Which GPUs are supported to recover PDF password?
When GPU client is activated?
GPU client is activated only if password definition contains '*' (regular repetition symbol). All another passwords are tested on CPU.
