Certificate revocation means that the certificate has expired before the date stated on the certificate, e.g. if the smart card or PC is lost. Revoked certificates are listed in the CRL (Certificate Revocation List). The issuance of CRLs is governed by the relevant I.CA certification policy for qualified or commercial certificates, in accordance with Act No. 297/2016 Coll. I.CA does not currently make this information available via FTP and LDAP.
