VellumPdf.Signing

NuGet CI

The digital-signature add-on for VellumPdf, a dependency-free PDF library for .NET 10 implemented clean-room from ISO 32000. It applies PAdES / PKCS#7 detached CMS signatures to a VellumPdf.Kernel.PdfDocument or a VellumPdf.Layout.Document.

  • PAdES levels B-B, B-T (RFC-3161 signature timestamp), B-LT (embedded OCSP/CRL in a /DSS), and B-LTA (archive document timestamp).
  • Pluggable timestamp (ITimestampClient) and revocation (IRevocationClient) clients, with HTTP implementations included.
  • Keeps the core zero-dependency: this package is the only one that references System.Security.Cryptography.Pkcs.

Install

dotnet add package VellumPdf.Signing

Usage

using System.Security.Cryptography.X509Certificates;
using VellumPdf.Fonts;        // Standard14
using VellumPdf.Layout;       // Document
using VellumPdf.Layout.Core;  // TextStyle
using VellumPdf.Layout.Elements;
using VellumPdf.Signing;

using var doc = new Document();
doc.SetDefaultFont(new TextStyle { Font = Standard14.Helvetica, FontSize = 11 });
doc.Add(new Paragraph("Signed with VellumPdf."));

var settings = new PdfSignatureSettings
{
    Certificate = X509CertificateLoader.LoadPkcs12FromFile("signer.pfx", "password"),
    Level = PadesLevel.B_T,
    TimestampClient = new HttpTimestampClient(new Uri("https://timestamp.example/tsa")),
    Reason = "Approved",
};

using var output = File.OpenWrite("signed.pdf");
doc.Sign(output, settings);

Roadmap

Milestone Scope
1.11 — Barcodes completeness (this release) Closes the #155 completeness backlog: QR Kanji mode, QR Structured Append, Compact (Truncated) PDF417, Macro PDF417, and Code 128 FNC4 / extended Latin-1.
2.0 — Breaking changes Strong-named assemblies (#53) and an async I/O surface for Save/Sign/loaders (#54); both change assembly identity or the public contract, so they wait for a major version.
2.1 — PDF reader (structural) VellumPdf.Reader grows classic and cross-reference-stream parsing, object streams, and encryption support, with a fixture corpus proving it against real-world files (Epic #100).
2.2 — PDF content extraction Text and image extraction on top of the reader.
3.0 — Read-modify-write A unified round-trip document model that supersedes the write-once PdfDocument, so existing PDFs can be opened, edited, and saved back (Epic #101).
