DigiDoc 4 features a more modern design that is easier to use, and the first time it is launched, the application provides a good overview of the opportunities the new version provides, said the RIA.

"The biggest change compared to the previous version is that the previous three applications have been replaced for users with just one," said RIA eID software project director Tõnis Reimo.

The new application covers all ID card-related activities, including administrative functionality, documment encryption and digital signatures.

The application is available in Estonia, English and Russian and can also be used with multiple ID cards at once.

Both DigiDoc 3 and DigiDoc 4 will remain in concurrent use, but the RIA recommends anyone who uses their ID card for digital signature purposes, to encrypt documents, or wants to verify the validity period of their ID card's certificates to begin using DigiDoc 4 by the end of the year at the latest.

"We will no longer be updating DigiDoc 3, which is why DigiDoc 4 is no doubt the better and more modern tool for processing documents with ID cards," Reimo explained.

The new ID card application can be downloaded here (link in English). Beginning in June, computers will begin automatically offering the newest version.

The RIA is accepting user feedback for improvement of the application through June 1.
