Password Security 3.4.0 (Shareware)

A-PDF Password Security is an application that allows users to change the passwords of PDF documents. It makes use of 128-bit and 40-bit encryption to protect important documents and keep them confidential. This prevents unauthorized users to access the contents of a PDF file. Aside from adding passwords, the program can also remove passwords from a PDF file. This can only be done if the user has the password for the document.

The program has a simple user interface. The main window offers three tools. They are:

• Single PDF Document Security – This tool is used for adding or removing a password for only one PDF document.
• Batch PDF Documents Security – This tool is for adding or removing passwords for several PDF documents.
• Hot Directory – this feature allows users to monitor a directory. Copied documents are encrypted and then automatically sent to an output directory.

The application’s security settings allow users to choose the security level for passwords, add a password, and change the permissions for the PDF file (changes, printing, copying). Other options the program offers include printing, document assembly, content accessibility, authoring, and many others. A-PDF Password Security also allows users to change the metadata of PDF documents.
