What is pdf encryption?
Portable Document Format is a non-editable file format which is platform independent. This file format is transferable across multiple platforms irrespective of the configuration of the system. The Portable Document Format is a computer application with which you can transmit huge volumes of data to the physically distant people. The main purpose of designing this application is to facilitate paperless office. With the use of this file format, you can eliminate the use of the paperwork. The use of these compatible and portable electronic files enables you to effectively manage vast amount of data on any subject.
The most advantageous feature of the Portable Document Format is that a person can easily protect the contents of the document. The protection is one of the most preferred and relevant feature of this document. Encryption refers to the process of encoding information so that the person with an authenticated key can decode this information. This kind of information is encoded and decoded in the form of passwords, certificates or digital signatures.
A user with a correct password can have access to the files. When you encrypt the files with the certificates, it means a person with the matching certificate can open the PDF documents. There is another option to encrypt the Portable Document Format. A person can also protect the PDF documents by using digital signatures. In case if an author wants to make use of the passwords, he can make use of two types of passwords which are called ‘user password’ or ‘owner password’. In case if you use a former one, a person having access to the PDF file need to enter the correct password in order to open the PDF file. If an author encrypts the file using ‘owner password’ a person can open the PDF file without the password but needs the same to enable any feature (such as copying, editing or modifying) which has been disabled by the author. There are many PDF converter tools available in the market that helps a user to employ either of these methods to encrypt the files. In this format, a person can protect the contents of the documents and save confidential data from being hampered.
