A-PDF Password Security is a desktop utility program designed to manage the password security of existing Acrobat PDF files. It empowers users to protect their PDF documents with robust 128-bit encryption or to remove existing password protection, supporting both 40-bit and 128-bit RC4, as well as 128-bit AES encryption for decryption. The software efficiently handles both single and batch documents, offering convenient features like a password pool for automated decryption attempts and hot directories for real-time encryption of saved files. Beyond basic encryption and decryption, it allows users to modify PDF file restrictions, controlling permissions such as printing, content copying, and document alteration. Additionally, the utility provides capabilities for batch editing PDF metadata, including Title, Subject, Author, and Keywords, and enables the setting or removal of expiration times and dates for PDF files. A-PDF Password Security is a standalone application, eliminating the need for expensive third-party software like Adobe Acrobat Pro, making it a cost-effective solution for comprehensive PDF security management.
