Parallel Password Recovery (PDF module) v 2.5

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.

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 x86-processors, especially for new Core i5/i7 and Bulldozer architecture including SSE, AVX, XOP and AES-NI extensions.

Uses the GPU power

Supports most of modern GPU cards using NEWOpenCL 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 1.7 ExtensionLevel 8 (Acrobat X-XI) files, including AES encryption, Unicode passwords, compressed files and unencrypted metadata
