              Revoked Self-issued Certificates  | 
            
            
              Self-issued certificates are CA certificates in which the issuer and subject are the same entity. Self-issued certificates are generated to support changes in policy or operations. 
                As eCA self-signed a new eCA –G2 self-signed certificates on Nov. 17, 2015 and Google suggested that the CAs using SHA-1 in cross-certs create new cross-certs signed with SHA-2 in March 2015 34th CA/Browser Forum F2F meeting. After the approving of ePKI Policy Management Committee, eCA revoked below two SHA-1 self-issued certificates on Nov. 17, 2015. eCA issued new self-issued certificates and published in repository.  |
