Digital signing

  • Signing with an ID-card

    Several signing plugins have been developed for different operating systems and browsers: components and sample applications.

  • BDOC, CDOC and ASICE DigiDoc file formats

    An overview of DigiDoc container formats supported by different versions and components of the ID-software can be found on the DigiDoc container format life cycle page. There is also a sample file for each format.

  • Certificates required for verifying digital signatures

    In order to verify files that are digitally signed with an ID-card or a mobile-ID and/or digitally stamped, all of the root certificates, certifiers and OCSP-responder certificates used to date must be configured in the information system.
