Adobe's electronic document format - PDF - is very common on the Internet and as a corporate format. Presentations, magazines, manuals and various documents are typeset in this format. A password can be set on PDF files.
Instructions
Step 1
At the request of the author of the document, when compiling the file, the author can set a password to open the text or presentation inside the document. Also, the password is put on secret or paid documents, statistical data, etc. You can get a password in two ways. The first way is the official one - to find out the password from the author, for a fee, if possible. The second method is to brute-force a password if you cannot contact the author, if the author is yourself and you forgot the password, or in other cases. Brute is brute-force password brute-force using special software. Finding in this way can take a long time, depending on the complexity of the password, as well as on the speed of the computer's processor.
Step 2
For brute-force password cracking, use the “PDF Password Remover” utility from the manufacturer VeryPDF. The program removes protection from copying and disassembling, and also removes the prohibition on changing and printing a document. Also “PDF Password Remover” removes a unique password for reading a PDF document. The program can work in batch mode, i.e. you can list PDFs by adding them to “PDF Password Remover,” and the utility will remove digital restrictions in turn, until all files are unprotected.
Step 3
Another representative of PDF decryption software is “Adult PDF Password Recovery”. The program selects passwords to remove protection for opening a document, as well as for its subsequent editing, printing and copying data. Adult PDF Password Recovery supports Acrobat 6.0 and above - PDF1.5, can work in batch mode. The utility has support for Adobe Standard 40 Bit Encryption and Adobe Advanced 128 Bit Encryption, which theoretically will help you find a password for almost any file.
