Own encryption provider for the Windows platforms and OpenCS extensions for third-party cryptosystems.

Many European financial and legal organizations use their own encryption units and means of cryptography; work with them is only possible from a specific software (no support for standard API). This significantly limits the possibility of using these tools for signature, encryption and two-factor authentication.

Our own Windows-crypto has been developed, as well as expansion OpenCS-library (implementation of PKCS15 – Standard) to work with more than 40 encryption units and key containers of European manufacturers. This made it possible to use the known software products focused on industry standards – for example, using a crypto has become possible to perform digital signing using the “non-standard” smart cards of PDF-documents directly from Adobe Acrobat.

Cryptographic is integrated into the whole range of soft Xpansion own PDF products, and is also available as a separate product.


Electronic signature support in the Perfect PDF and PDF xPansion SDK products


The entire line of soft Xpansion PDF-products (desktop product family Perfect PDF, server products family of soft Xpansion Render Center, a library to work with a PDF documents, SDK for third-party developers – PDF Xpansion SDK) fully implements support for digital signing and encryption of documents in accordance with the PDF-standard.
In particular, it supports:

  • Signing of an entire document or specific pages
  • Signing documents using keys stored in Windows-store external files, encryption containers, as well as directly with the use of encryption units such as smart-cards
  • Integration of time-stamp labels in digital signatures from external TS-servers
  • Verification of digital signature / signatures chains, including an analysis of chains of trusted certificates and certificate revocation lists, the visualization of digital signatures and their status
  • Encryption the whole document or a part of it in full compliance with the PDF specification
Server Render Center line solutions come with their own implementation of TimeStamp-server and tools for generation of self-signed certificates (in demand for internal workflow of small and medium businesses).

EMC Corporation licenses soft Xpansion PDF SDK for working with PDF-content in the EMC Captiva line of products (including the possibility of a digital signature).

At ING Bank (Central and Eastern Europe), soft Xpansion PDF Render Center server solution is used to digitally sign email sent through the client-bank customers of the Bank.
