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.

NEWNow with Unicode and x64 support!

Features and benefits

Local 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 architecture

Uses 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!
