PDF Password Crack Pro

The PDF Password Cracker Professional edition is a powerful software that provides efficient options to retrieve passwords for PDF files. Its features include brute-force and dictionary attacks that are capable of searching for "owner" and "user" passwords. Though these attacks are optimized for speed, it's important to note that recovering long passwords may take an unreasonable amount of time.

One of the most impressive features of this software is its Key search attack. This attack guarantees decryption, regardless of the password length and complexity, for PDF files that use 40-bit encryption. This attack takes about three to four days on fast CPU systems, making it an ideal solution for anyone trying to retrieve passwords from highly encrypted PDF files.

The software is designed for ease of use. You can drag and drop PDF files onto the interface without the need for Adobe Acrobat software. This software is supported by Windows 98, ME, NT, 2000, XP, and 2003 systems. It also supports PDF 1.6 (Acrobat 7.x) files, including 40-bit RC4 decryption, 128-bit RC4 decryption, compressed files, and unencrypted metadata. Additionally, it supports Adobe Standard 40-bit Encryption and Adobe Advanced 128-bit Encryption.

The program recovers user passwords required to open the file, and it allows you to use either Brute-Force or Dictionary attacks to recover the password. The software features additional user dictionaries, case changes, multiple mistypes, and other modifications for each dictionary word. The program automatically saves password search states and can resume after a stop or a crash.

The software also supports patterns that can be used to minimize search time if any part of the password is known. This feature helps in the recovery of passwords from PDF files effectively. It's also worth noting that non-English characters in passwords are supported by this software.

In conclusion, the PDF Password Cracker Professional edition is an impressive software that offers powerful features to retrieve passwords from encrypted PDF files. Its ease of use, support for non-English characters, and efficient attack methods make it a top choice for anyone looking for a reliable and effective solution to retrieve passwords.
