RIA DigiDoc

RIA DigiDoc is an application that allows you to digitally sign documents using an Estonian ID-card via NFC, Mobile-ID or Smart-ID, verify digital signatures, encrypt documents, and open, save and share files on your mobile device. Encryption and decryption in RIA DigiDoc are available only with an Estonian ID-card. Containers with .ddoc, .bdoc, .asice and .cdoc extensions are supported.

With RIA DigiDoc, you can view ID-card certificate information, check certificate validity, and change PIN and PUK codes. The “My eIDs” menu displays the cardholder’s details and information about the validity of the ID-card.
