PDFs do not need to be open in Revu when the process is run. This process can be performed on multiple PDFs at the same time. Some actions, such as certifying or digitally signing a document, automatically secure it. Some functions, such as splitting the document or extracting pages, cannot be performed without first breaking its security and doing so will revert the PDF to an unsecured state. This entry was posted in PhantomPDF, Product blog and tagged encryption.Security can be set to restrict access to the PDF or to require a password for modification. Using this method, only viewers with a specified digital certificate installed on their system can access the file.įoxit PhantomPDF provides a user with both methods, allowing the user to determine which technique best meets their needs. A digital certificate is an electronic identification that establishes credentials on the Internet, which are provided by a certification authority. The difference is that the author does not provide a password during encryption, but instead specifies a digital certificate. The viewer will then have access to the document based on the rights that the author defined during encryption.Ĭertificate encryption works very similarly. The document will decrypt when a viewer provides the correct password.
This protection also allows the author to limit the rights of what the viewers of the document can do, such as editing, printing, and copying. Password encryption requires the author to provide a password when encrypting the document. The two most common viewer validation techniques of an encrypted file are password encryption and certificate encryption.
When a person validates that themselves as an intended viewer of the document, the file will be decrypted, meaning the scrambled information will be re-arranged into its original format. Encryption uses a mathematical key to scramble the information in a PDF file so only the intended viewers can access them. One of the most common ways is to use encryption. There are many ways to protect PDF files containing confidential information.
