Documentation

: All services have CP and CPS documents and for several services Microsec has Disclosure Statement, which is an abstract of the CPS.
In case of multipurpose roots Microsec e-Szigno Root CA 2009 and e-Szigno Root CA 2017, several type of certificates are issued under each of the root CAs, but from different subordinate CAs. The details can be found in each CPS document in chapter 1.3.1. All of the listed documents are relevant for each multipurpose root CA.
According to the new Root Program requirements, Microsec created dedicated Root hierarchies for TLS, S/MIME and CodeSigning.
For the DV and OV type of TLS certificates the following service is relevant:
• eIDAS conform Certificate for Website Authentication
For the EV certificates the following service is relevant:
• eIDAS conform Qualified Certificate for Website Authentication
The domain validation rules and other TLS related regulations can be found in these CPS documents.

CCADB-published contact mechanisms for certificate problem reports and CA incident reports.
