Move to digital signature

Digital signature (PKI) is the recommended signature mode, and the only one this help center documents. The options of signature without PKI are deprecated.

What changes

Option	Purpose	Status
DoNotEncryptPDF	Do not encrypt the signed PDF	Deprecated
DoNotAppendCertificateToFile	Do not append the certificate to the file	Deprecated

These options still work for now. With digital signature, you do not need to set them: PkiFileHelper sets them to false itself.

How to migrate

1. Install the signature module: Choose your package.
2. Certify your PDFs with PkiFileHelper instead of building the files to sign yourself. The right encryption and certificate settings are applied automatically.
3. Remove DoNotEncryptPDF and DoNotAppendCertificateToFile from your code.
