Abstract
The invention relates to an information processing system for decrypting an encrypted PDF file. The information processing system comprises a file input module, a decrypting module, a file output module and a storage module, wherein the decrypting module is connected with the file input module, the file output module and the storage module respectively. Compared with the prior art, the PDF file is decrypted, the problem that the encrypted PDF file cannot be opened in other production software is solved, the encrypted PDF file can be processed rapidly, and a processing flow of follow-up work is accelerated.
Description
Technical field
The present invention relates to information security field, especially relate to a kind of for the information handling system that the pdf document of encrypting is decrypted.
Background technology
PDF full name Portable Document Format, it is a kind of electronic document format, this file layout and operating system platform are irrelevant, can be general in any operating system, and the pdf document form can and be independent of equipment and the graph image of resolution etc. is encapsulated in the file and can comprises electronic information such as hypertext link, sound and dynamic image with literal, font, form, color, support the speciality file, integrated level and safe reliability are all higher, and this becomes in a kind of file layout that is widely used it.
At present, the file that many clients provide is PDF mostly, and there is a problem in the file that some client provides, be exactly that pdf document has password, so just when subsequent treatment, cause, need contact customer that password is provided or the unencrypted file is provided again, cause time delay.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists can the pdf document of any encryption be decrypted, the information handling system that its password is removed.
Purpose of the present invention can be achieved through the following technical solutions:
A kind ofly comprise document input module, deciphering module, file output module and memory module for the information handling system that the pdf document of encrypting is decrypted, described deciphering module is connected with memory module with document input module, file output module respectively.
Described deciphering module is equipped with the PDF decryption software.
Described document input module is used for obtaining the pdf document of encryption, is sent to deciphering module then and is decrypted by the PDF decryption software, be stored in the memory module through the pdf document after the deciphering, and by the output of file output module.
Compared with prior art, the present invention is by being decrypted pdf document, solved to encrypt pdf document and can not make the problem of opening in the software at other, can this type of pdf document through encrypting of fast processing, accelerate the treatment scheme of follow-up work.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of for the information handling system that the pdf document of encrypting is decrypted, comprise document input module 1, deciphering module 2, file output module 3 and memory module 4, deciphering module 2 is connected with document input module 1, file output module 3 and memory module 4 respectively, wherein, deciphering module 2 is equipped with the PDF decryption software, can select softwares such as PDF Password Remover for use.Document input module 1 is used for obtaining the pdf document of encryption, is sent to deciphering module 2 then and is decrypted by the PDF decryption software, be stored in the memory module 4 through the pdf document after the deciphering, and by 3 outputs of file output module.
The present invention is by being decrypted pdf document, solved to encrypt pdf document and can not make the problem of opening in the software at other, can this type of pdf document through encrypting of fast processing, accelerate the treatment scheme of follow-up work.
