On February 14, 2019, we changed the signature algorithm for the ECC certificates from SHA256ECDSA to SHA384ECDSA in order to meet Mozilla’s root policy. This change applies to both EV ECC and OV ECC certificates.
On February 15, 2019, we replaced “DigiCert ECC Secure Server CA" with “DigiCert Secure Site ECC CA-1” in order to issue ECC certs with SHA256ECDSA.
|Type||Hierarchy||Old Intermediate CA||Current Intermediate CA||Signature algorithm issued before Feb 14, 2019||Signature algorithm issued on and after Feb 15, 2019|
|EV||ECDSA with RSA root||DigiCert ECC Extended Validation Server CA||No change||sha256ECDSA||sha384ECDSA|
|EV||ECDSA with ECC Root||DigiCert Extended Validation CA G3||No change||sha256ECDSA||sha384ECDSA|
|OV||ECDSA with RSA root||DigiCert ECC Secure Server CA||DigiCert Secure Site ECC CA-1||sha256ECDSA||No change|
|OV||ECDSA with ECC Root||DigiCert Global CA G3||No change||sha256ECDSA||sha384ECDSA|
