Notes about the DDOC file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The DDOC file type is primarily associated with 'DigiDoc' by OpenXAdES Project. DigiDoc is a universal system for giving, processing and verifying digital signatures created by AS Sertifitseerimiskeskus. It can be connected to any existing or new software, but its components are also a stand-alone client program and web portal. The DigiDoc client is available to anybody to download for free. Anyone can use it to verify digital signatures or, if you have an Estonian ID card and smart card reader, also to give digital signatures.
