All about PDFSIG Files
The PDFSIG file type is primarily associated with PDFsharp.
What is a PDFSIG file?
PDFSIG files mostly belong to PDFsharp. PDFSIG files are containers that hold a digital signature within a PDF structure. They use the Portable Document Format for their content, but include extra data that verifies the document's authenticity and checks that it has not been altered.
When you open a PDFSIG file with a capable PDF viewer, you see a document that carries cryptographic data used for validation. This ensures that the document is genuine and its contents remain unchanged.
The file structure is based on standard PDF elements with embedded signature data. It acts as a secure container for digital certificates and cryptographic hashes. Tools associated with PDFsharp may help create or verify these signatures. FilExt.com tip: Such functionality is important in legal, financial, and business applications where document integrity is essential.

Programs that open and convert PDFSIG files:
- PDFsharp
See the previous paragraphs to learn more about the main application. PDFSIG files are often referred to as PDFsharp data files because this type of file is primarily created or used by this software.
- PDF software supporting digital signatures (e.g., PDFsharp)A .PDFSIG file is a specialized PDF document incorporating digital signatures. These signatures, based on cryptographic principles, serve to verify the authenticity and integrity of the document's content, ensuring it hasn't been tampered with since signing. Digital signatures within .PDFSIG files provide a robust mechanism for validating the sender's identity and affirming the document's untampered state. This file format is classified as Document.
Technical Data for PDFSIG File Extension
a pdfsig digital signature container is a special file format and should only be edited and saved with the appropriate software.
