I.CA Certificates
You can install all current I.CA root certificates by running the I.CA RootMan application. If installing I.CA root certificates in Mozilla Firefox, use the instructions below.
On September 1, 2015, První certifikační autorita, a.s. started providing certification services in the area of issuing certificates in a two-level hierarchical structure. On 1.7.2017 it stopped providing services in a flat structure. Within the hierarchical structure, I.CA issues root certificates and subsequently subordinate certificates for the respective services it provides.
Once installed on a PC, the root certificate is listed as a Trusted Root Certificate Authority and allows for subsequent automated verification of client certificates issued by the I.CA in the system.
