In this tutorial, we learn how to sign a PDF document with a certificate-based digital signature in Adobe Acrobat DC. To do this, you need to download and install Adobe Acrobat DC from its original website for free. A digital ID is required to sign a document with a certificate-based digital signature, containing information such as your name, email address, organization name, serial number, and expiration date. Digital IDs in Adobe Acrobat are used to certify documents or add digital signatures. To add or create a digital ID, go to the edit menu, choose preferences, click on signatures, select digital IDs, and click the add ID button. If you already have a digital ID from your organization, you can add the digital ID file.
