Protect Documents with PDF Signing

PDF signing is the process of adding a digital signature to a Portable Document Format (PDF) file to help verify the identity associated with the signing certificate and confirm that the signed content has not been altered since the signature was applied. Digital signatures help verify a document's authenticity and integrity while providing evidence of who signed it, making them suitable for contracts, approvals, compliance workflows, and other business processes that require trusted electronic documents. By reducing reliance on printed paperwork and manual signing, PDF signing can also improve efficiency while helping organizations meet security, audit, and regulatory requirements.

Several ASP.NET Core PDF components enable PDF signing, including:

• Document Solutions for PDF by MESCIUS enables developers to apply and validate digital signatures in PDF documents, with support for timestamping and Long-Term Validation.
• Telerik UI for ASP.NET Core PdfProcessing (part of Telerik UI for ASP.NET Core) enables applications to sign and validate PDF documents using X.509 certificates.
• ImageGear for .NET by Accusoft enables applications to create and validate digital signatures, helping protect document integrity and authenticate signed PDF content.
• Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) enables apps to sign and validate PDF documents, with support for visible signatures and timestamps.
