[Notice] Announcement on Discontinuing SHA-1 Root Certificate Issuance

Dear Customer,

 Due to the security vulnerabilities present in root certificates using the SHA1 signature algorithm, Mozilla will remove trust in root certificates including DigiCert Assured ID Root CA, DigiCert Global Root CA, and DigiCert High Assurance EV Root CA on April 15, 2026. To further strengthen digital certificate security standards, we will stop issuing DigiCert certificates under the SHA1 root by default starting April 15, 2025.

 We recommend that customers currently using the above root certificates reissue or replace them with the latest DigiCert G2 root certificates before the trust removal takes effect. If you have upcoming renewal or new purchase needs, we recommend prioritizing DigiCert G2 root certificates. If you have any questions about encryption algorithm standards or operation procedures, you can log in to the official website to refer to the documentation or contact the technical support team. Thank you for your understanding and support!
