DigiCert Root Certificate Upgrade Notice- August 18 2024

Dear ZOLOZ Customer,

Due to Mozilla updating its root certificate trust policy, which requires all globally trusted CA root certificates to be replaced at least every 15 years, some of DigiCert's old root certificates will be gradually upgraded to DigiCert Global Root G2 starting from August 18, 2024. To ensure your continued use of ZOLOZ's services, please read the following carefully.

Impact of the Upgrade

  • DigiCert Global Root G2 uses the SHA256 signature algorithm, enhancing security.
  • Certificates issued before August 18, 2024, can be used normally; from August 18, 2024, DigiCert brand SSL certificates will be issued through new root and intermediate certificates.
  • App business and IoT terminals with pre-installed root certificates will be affected. It is recommended to switch to the system's built-in trust store for verification and ensure it contains the DigiCert Global Root G2 certificate.
  • The new root system is still compatible with current mainstream operating systems and mobile devices. The known mainstream environment compatibility is as follows:
