The Protection tools are used to add/remove digital signatures, certified signature fields, timestamps and passwords to input documents:
Add Digital Signature uses a certificate-based digital ID to add and sign signature fields in input documents.
Certify PDFs adds certified signature fields to input documents.
Clear All Digital Signatures removes digital signatures from input documents.
Secure PDF adds password security to input documents.
Timestamp PDFs adds document-level time stamps to input documents.
