You can download the SDX Verify and SDX Verify M2 application package installer from the page below.

The SDX Verify client module’s job is to verify the authenticity of the document with CRL (certificate revocation list) management.

The SDX application contains digitally signed codes and components. The component with digital signature ensures the integrity of the code-component and the library. Any modification to the files – caused by either a virus or direct tampering – will be detected when running the application.

Main features:

• Verifying document integrity;
• Verifying electronic signatures;
• Verifying the timestamp on the document;
• Verifying the signer’s certificate and its validity, also the certifying organisation;
• Verifying compliance with the Electronic Signature Policy (ESP).

Usage

When opening a certified file (double click on an .SDXM file in Explorer) authentication starts right away. You can also right click on the desired file and choose ’Authentication – SDX’ from the pop- up menu. The embedded (signed) file can be viewed on the ’Content’ tab. If you directly start the program (SDX Authentication) it prompts for the desired SDX document, of course.
