These applications are designed for creating and processing qualified electronic signatures (QES), previously known under Act No. 215/2002 Coll. on Electronic Signatures as guaranteed electronic signatures (GES). They are used to authenticate electronic submissions and electronic official documents in accordance with Act No. 305/2013 Coll. on e-Government, Regulation (EU) No. 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC, and Regulation (EU) 2024/1183 of the European Parliament and of the Council of 11 April 2024 amending Regulation (EU) No. 910/2014 as regards establishing the European Digital Identity Framework.
The applications intended for creating QES comply with the relevant security, functional and content requirements for electronic signature creation applications set out in ETSI TS 119 101, Act No. 272/2016 Coll. on Trust Services, and the relevant standards of the National Security Authority of the Slovak Republic (NBÚ SR) concerning qualified electronic signatures. The supplier declares compliance with the requirements of ETSI TS 119 101.
D.Launcher v2.x – together with the new version of the D.Bridge JS libraries, v1.5, and the corresponding D.Bridge 2 web browser extension, it is used to launch and secure communication between the browser webpage and the QES components integrated into information system portal solutions. It also enables the automatic installation and updating of QES components on the Java platform, the required Java Runtime Environment (JRE), as well as its own automatic updates. By using more modern technologies, it addresses several technical issues encountered with D.Launcher v1.
D.Signer Suite – includes:
D.Viewer – an application used to view data structures for electronic data exchange, particularly electronic submissions, forms and their attachments intended for communication with the public administration of the Slovak Republic.
D.Updater – an application used to automatically check for available updates (i.e. newer versions) of the D.Suite/eIDAS package components for qualified electronic signatures on the .NET platform and to install them.
Client applications for qualified electronic signatures (D.Signer, D.Viewer, D.Sig XAdES Extender and ASiC Factory) are available for the MS Windows operating systems (.NET and Java), GNU/Linux (Java only) and macOS (Java only).
The D.Launcher v2 application is also available for all the operating systems listed above.
Mobile operating systems (smartphones and tablets), such as Android and iOS, are currently supported in combination with the Disig Web Signer Mobile application, but only when used together with the desktop D.Signer application (.NET or Java), from which the signing process must be initiated. Client applications that allow documents to be signed directly on mobile devices without initiating the signing process from a desktop application are planned for the future, provisionally during 2026.
The installation of client applications or plug-ins is required because, at present, no solution for signing documents with a qualified electronic signature is available for all mandatory supported web browsers that would function entirely within the browser without requiring the installation of an additional plug-in, extension or client application.
When creating a QES, the D.Signer application uses a Qualified Signature Creation Device (QSCD), such as an identity card with an electronic chip (eID card), a Starcos chip card, or a similar device. A list of certified QSCDs is available on the European Commission’s websiteOpens in a new window.
The software and drivers required for a QSCD, or for a card reader, are generally available on the website of the relevant trust service provider (formerly an accredited certification authority – ACA) that issued the qualified certificate to the user. Software for the identity card with an electronic chip (eID card) is available on the Software DownloadsOpens in a new window page or on the website of the Ministry of the Interior of the Slovak RepublicOpens in a new window.
Various applications from different vendors can be used to create qualified electronic signatures. However, to create a qualified electronic signature on the www.slovensko.sk portal and certain other public administration portals, the applications listed above may be required because they are integrated into the portals’ websites.
