Class PdfEditSecurity

Controls PDF editing permissions for password-protected documents. Defines what changes users can make without the owner password.

// Prevent ALL editing:
pdf.SecuritySettings.AllowUserEdits = PdfEditSecurity.NoEdit;
pdf.SecuritySettings.UserPassword = "read123";
pdf.SecuritySettings.OwnerPassword = "admin456";

// Allow only page management:
pdf.SecuritySettings.AllowUserEdits = PdfEditSecurity.EditPages;

// Allow full editing:
pdf.SecuritySettings.AllowUserEdits = PdfEditSecurity.EditAll;

Users with owner password always have full access
