Understanding PDF Encryption
PDF encryption is a process that secures a Portable Document Format (PDF) file by restricting access and protecting its contents from unauthorized users. This is critical for safeguarding sensitive information, such as financial documents, legal papers, and personal data.

PDF encryption typically comes in two forms: password protection and certificate-based encryption.

This is the most common method and involves setting a password that must be entered to open the PDF. There are two types:
- User Password: Needed to view the document.
- Owner Password: Allows the owner to restrict certain actions, like printing or editing.
Pros: Simple to use and widely supported.
Cons: Vulnerable if weak passwords are chosen.
Certificate-Based Encryption
This method uses digital certificates for encryption, offering a higher level of security, especially for organizations.
Pros: More secure than password protection.
Cons: Requires technical knowledge and can be complex to implement.
