A certification authority is an entity that issues digital certificates (electronically signed public encryption keys), facilitating the use of PKI (Public Key Infrastructure) by using its authority to confirm the accuracy of the information contained in the freely available public key. Based on the principle of trust delegation, we can trust the information stated in a digital certificate, provided that we trust the certification authority itself.

Many commercial certification authorities operate on the Internet and typically have their public keys embedded directly in web browsers and other applications, which simplifies users' decisions about the level of trust to assign to the web servers they connect to. There are also free certification authorities, as well as those governed by the laws of a given country, internal organizational policies, and similar regulations.

The most well-known Czech authorities are preloaded here — those that are generally trusted and most frequently approached for certificate issuance.

If you need to add another certificate, use the button — this will open the "Add Certificate to Directory" dialog, which guides you through the certificate import process.
