A digital signature is a cryptographic method for ensuring the authenticity and integrity of a document. Unlike a regular signature, a digital signature uses encryption to secure both the document’s content and the identity of the signer. Digital signatures on PDFs not only offer security but also save time, reduce paper waste, and make document management more efficient.
This article walks you through digitally signing a PDF using the Cloud .NET SDK, along with example code to help you use digital signatures and automation.
Steps to Sign PDF with Digital Signatures using .NET REST API
- Sign up and get your API credentials from the GroupDocs Cloud Dashboard
- Install GroupDocs.Signature Cloud .NET SDK using the NuGet package
- Configure your API credentials using the Configuration class
- Instantiate an object of the SignApi class for adding an e-signature
- Set up the digital signature options with SignDigitalOptions
- Define the input/output file settings in cloud storage with SignSettings
- Process the request to sign a PDF document digitally
Developers can use these steps and integrate digital signatures into PDF files in C# applications across Windows, Linux, and macOS. With the .NET REST API, automating the process of digitally signing PDF documents is straightforward. Plus, it offers flexibility to customize the signature’s appearance, scalability, and dynamic usage. While sending contracts, agreements, or important legal forms, you can be sure that the information has not been tampered with and that the signer’s identity is verified.
