PDF (Portable Document Format) has become the standard for modern office document exchange. Encrypting PDF files is a crucial method for protecting sensitive information, whether it's business contracts, financial reports, or personal identification data. Encryption ensures that only authorized individuals can access the content.
Purposes of PDF Encryption
-
Privacy Protection: Prevent unauthorized access and ensure sensitive information isn't compromised
-
Usage Control: Restrict printing, editing, or copying content to protect intellectual property
-
Regulatory Compliance: Meet requirements of data protection regulations like GDPR and HIPAA
-
Secure File Sharing: Ensure file security even when transmitted through insecure channels
