SC Secure Soft PDF Signer is a digital document signing application designed to apply cryptographic signatures to PDF files using X.509 digital certificates. It supports individual document signing as well as batch processing, allowing organizations to handle large collections of business records without signing each file manually.
The software is suitable for businesses, administrative departments, and professionals who need to authenticate electronic documents, process invoices, or maintain verifiable records. Its support for smart card certificates, timestamp authorities, and established digital signature standards makes it useful in certificate-based document workflows.
PDF Signer also provides configurable signature appearances, command-line parameters, and options for embedding certificate revocation information. These capabilities help users integrate PDF signing into existing processes while supporting signature verification and long-term document validation.
Software Overview
SC Secure Soft PDF Signer focuses on applying digital signatures to PDF documents using public key infrastructure (PKI). Users can select input and output directories to sign multiple files in one operation, making the application suitable for recurring document processing tasks such as corporate paperwork and invoice management.Digital signature settings include support for SHA-256 and SHA-512 hash algorithms, along with RSA keys of 2048 bits or greater. The software also supports timestamping through RFC 3161-compliant secure timestamps, helping establish evidence that a signed document existed in a particular state at a specific time.
For workflows that require extended signature verification, PDF Signer supports PAdES Part 2 and PAdES LTV. It can embed certificate revocation information obtained through CRL and OCSP mechanisms, helping verification systems assess certificate validity. Long-term validation support is designed to assist with checking signatures even after a signer's certificate expires or is revoked, subject to the available validation data and verification environment.
The application allows users to customize the visible signature's position and choose whether it appears on the first page, last page, or all pages. Its PKI-neutral design supports components from different vendors, including certificate authorities, digital certificates, certificate revocation lists, and smart cards.

What is SC Secure Soft PDF Signer used for?
It is used to digitally sign PDF documents with X.509 certificates, including processing multiple files in a batch. It also supports timestamping and features intended to assist with signature validation.Can PDF Signer sign multiple documents at once?
Yes. Users can select input and output directories to process an entire collection of PDF files in a batch.What certificate and cryptographic options are supported?
The software supports X.509 certificates, smart card certificates, SHA-256 and SHA-512 hashing, and RSA key lengths of 2048 bits or greater.What are PAdES LTV and timestamping used for?
PAdES LTV supports long-term validation of digital signatures. Timestamping provides evidence associated with a trusted timestamp authority, while embedded revocation information can help verification systems assess certificate status.Can the digital signature's appearance be customized?
Yes. The signature position can be configured, and users can choose to display it on the first page, last page, or all pages of a PDF document.Home Page
