PDF Password Recovery

PDF Password Recovery is a Windows application for restoring access to a password-protected PDF file. There are several modes of operation - dictionary search, mask search and full character search. You can specify the key length and character composition. Various encryption protocols are supported, including AES and RC4.

Selection parameters

After opening the program, you need to specify the path to the required document through the explorer. Next, select the type of attack and the corresponding parameters. It should be taken into account that a complete search can take quite a long time. It is recommended to specify the maximum number of parameters to reduce the number of variants. To reduce the selection time, you can specify known parameters. For example, you can explicitly specify the type of characters used, as well as the length range. If it is known for sure that service characters were not used, they can also be excluded.

Restoration

To optimize the internal algorithm, you can specify the type of processor used. This will maximize the allocation of available resources and increase the enumeration speed. Also, task distribution allows you to reduce the overall load on the hardware. It is possible to save the current state of work to resume it later. It is possible to perform enumeration only at night time without interfering with the main work. During the scanning process, basic statistics and the approximate time until the selection is completed are displayed.
