Developer’s Description

By Thegrideon Software
Recover passwords and remove restrictions from PDF documents.
PDF Password by Thegrideon Software is advanced and extremely fast password recovery, decryption and restrictions (e.g. no copying, no printing, no editing) removal tool for .pdf documents. All standard .pdf encryption methods are supported upto the latest used in Acrobat XI. PDF files without or with known (user) password to open can be instantly saved with restrictions cleared. PDF files with 40bit encryption can be decrypted with guarantee. The set of configurable methods are available for password recovery of pdf files with (user) password to open and 128 - 256bit RC4 or AES encryption: dictionary (with several languages included), Brute-force with length and charset selectable and mixed (combinations of independent parts based on dictionary, brute-force or fixed). Virtually endless number of combinations for mixed attacks. Advanced keyboard layouts-aware recovery technique (on the fly conversion from one keyboard layout to another). Char replacement option (e.g. S,s with $ or Z,z with 2). Highly optimized code and GPU (AMD, NVIDIA, Intel) utilization guarantees fastest recovery speed. Latest Intel HD Graphics integrated GPUs can be used for password recovery acceleration. For example password recovery speed for most common protection method (Adobe 5.0 - 7.0) on Intel i3 4130 + integrate Intel HD 4400 GPU + NVIDIA GTX 470 = 430 000 + 220 000 + 1 100 000 = ~ 1 700 000 passwords per second.
