Timestamping service

The timestamping service is a solution which proves that certain data exist at a certain time. Therefore, this is widely used with digital signing (in order to verify the legality of the document) and archiving solutions, where the objective is to keep guaranteed information unchanged.

Timestamping uses Public Key Infrastructure and reliable timing sources to provide secure and reliable information that complies with international standards (RFC-3161). The timestamping service is an HTTP service where timestamping is submitted as an HTTP POST query.

In Estonia, the service is provided by SK ID Solutions AS.
