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 should be used that is designed especially to gain maximal recovery rate. It is world’s first software with GPU acceleration to recover 128-bit PDF encryption!
- 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 of versions efficiently vectorize 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 all modern processors, including Pentium, Athlon and especially for Core 2 architecture, resulting in rate of 1.000.000 passwords per second on Quad-core computers. In the 1.5 version NVIDIA CUDA GPU support added, resulting in fantastic rate up to 70.000.000 passwords per second on modern GPU.
- All PDF versions support: Parallel PDF Password Recovery supports all PDF versions up to newest PDF 1.7 ExtensionLevel 3 (Acrobat 9) files, including AES encryption, Unicode passwords, compressed files and unencrypted metadata.
