Most solutions were either proprietary or had restrictive licenses, making it difficult for us to use them in our projects.<p>That's why we decided to create open-pdf-sign - a simple, easy-to-use tool for signing PDF from your CLI. We designed it to be user-friendly for developers, with a permissive license allowing easy integration into any project.<p>We also added a configurator that configures your Nginx server. It will automatically install and configure your Nginx so all your PDFs will be signed with your SSL certificate on the fly. You can even use your existing Let’sEncrypt certificates.<p>We believe that open-pdf-sign will be a valuable tool for any developer looking to quickly sign PDFs on their webserver or with their project. Give it a try and let us know what you think!<p>Thomas & Philipp
