Digital stamping means digital signing with an e-Stamp designed for legal persons. The service is offered by SK ID Solutions AS in Estonia.
As of the enforcement of the eIDAS regulation on 1 July 2016, SK has been entered in the trust list as a qualified e-Stamp certificate service provider.
An e-Stamp, which is used to certify digital documents, confirms that an electronically forwarded document or other information indeed comes from the institution that sent it. An e-Stamp confirms that the respective institution is linked to a specific digital document and the document has not been changed.
E-Stamps can be used with and without digital signatures. By using the e-Stamp certificate with a person’s digital signature, you can be certain that the document’s signatory is authorised to sign documents on behalf of the respective company.
SK issues e-Stamp certificates for both crypto-sticks and Hardware Security Modules (HSM) with the FIPS 140-2 or Common Criteria certificate.
Find additional information on e-Stamps on the SK website: Digital stamp service.

- Digital stamp use instructions
- suitable for cases that do not involve mass signing because the user must enter the crypto-stick’s PIN upon each instance of stamping.
