Sign PDFs using external signatures with Docotic.Pdf 9.3

News post

Updated on March 12, 2024

We have released Docotic.Pdf 9.3 and its add-ons on our site and on NuGet.

The main new feature of this release is the ability to sign PDF documents using external signatures. You can use smart keys, USB tokens, and HSM devices to sign PDFs with digital signatures. We added new sample codes that show how to sign PDF documents using AWS KMS, sign PDF documents using Azure Key Vault, and sign PDF documents using PKCS#11 driver.

Version 9.3 fixes trim warnings and AOT compatibility issues. This improves support for trimmed and ahead-of-time compiled self-contained applications.

In response to customer reports, we decided that the library should no longer automatically detect and attach to a configured logger. Instead, we introduce the new free Docotic.Logging add-on for you to use explicitly. We have updated the Logging with log4net and the Logging with NLog code samples to show how to receive log messages from the library.

The HTML to PDF add-on now uses Chromium 121.0.6167.85. And the add-on now explicitly depends on the Newtonsoft.Json library. Previously, this dependency was merged into the add-on DLL. Please check your app dependencies if you use the add-on from ZIP. You don’t have to do anything if you use the add-on as a NuGet dependency.
