Digital signing with Finnish ID-cards

Did you know that DigiDoc4 allows you to conveniently and rapidly verify digital signatures given with the Finnish ID-card and sign documents using the Finnish ID-card?

Verifying Finnish digital signatures

The DigiDoc4 Client makes it possible to verify signatures given with the Finnish ID-card if they are in BDOC or ASiC-E format.

Your DigiDoc4 does not need to be configured additionally – the verification of the digital signatures takes place exactly as for all other documents.

NOTE: The signature given with the Finnish ID-card is an electronic signature, and not a digital signature considered equal to a handwritten signature, as under Estonian law.

Electronic signatures given with the Finnish ID-card have AdES/QC signature level and as a result it does not meet the requirements for the highest signature level as defined as eIDAS. Basically, a signature given with the Finnish ID-card is not equal to a handwritten signature, and DigiDoc4 will display the following warning about signature level: kehtiv (piirangutega) – valid (with limitations).
