Guaranteed PDF Decryptor

Guaranteed PDF Decryptor is a lightweight application able to remove some of the restrictions applied to a PDF document. By some, it is highlighted that not all encrypted PDFs are breakable, as there are security levels that cannot be bypassed by this tool.

First of all, this utility is intended for light security parameters like editing or reading restrictions, which can be removed without any issue. Password-protected documents can be bypassed as well, as long as there are user passwords and the Acrobat version is supported.

Third-party plug-ins that offer encryption are not guaranteed, as well as encrypted e-books. Also, during testing, the encryption proved to be impossible to unlock, issue prompted by the app itself.

However, 40-bit encryptions are breakable, but the process will require up two days of processing, a process that can be accelerated only by high-end hardware, mostly GPU-related.

Besides the longer bypass times for encrypted documents, which, for some users can look a little bit aggressive, Guaranteed PDF Decryptor seems to be a useful utility for the other types of restrictions. The operation is based on the drag&drop feature, which saves time and avoids bothering with cumbersome menus.
