Syntax

public sealed class SignaturePermissions : Enum

The SignaturePermissions enumeration in IronPDF declares what further modifications a viewer may make to a digitally signed PDF without breaking the signature.

Part of the IronPdf.Signing namespace, the 3 members are NoChangesAllowed, AdditionalSignaturesAndFormFillingAllowed, and AdditionalSignaturesFormFillingAndAnnotationsAllowed, ranging from a locked document to one that still accepts countersignatures and annotations. Assign a value to PdfSignature.SigningPermissions before signing.

See Signing PDFs for full C# usage.
