About This Feature
Overview
Certificate Encryption is a document protection feature in WPS PDF that encrypts PDF files with digital certificates. During setup, you can choose a digital certificate, configure encryption options and permissions, and then save the protected file.
Core tasks include:
- Use Certificate Encryption: apply certificate-based protection to a PDF for controlled access.
- Add a Certificate: import a
.pfxor.p12certificate file and verify it with its password before using it for encryption.
This feature is useful for internal file circulation, contract sharing, policy distribution, and other PDF workflows that need certificate-based access control. It helps reduce unauthorized access risks and keeps certificate selection and permission settings in one workflow.
