DigiCert 品牌根证书停用G1,改用G2

受全球知名信任库 Mozilla 的根证书最新信任策略(全球所有 CA 的可信根证书生成后最少 15 年更换一次,超过时间的可信根会逐渐被 Mozilla 停止信任)影响,DigiCert 将逐步停用旧根体系(G1)颁发 TLS/SSL 证书,并开始使用新根体系(G2)颁发 TLS/SSL 证书,以确保 TLS/SSL 证书在 Firefox 浏览器中继续受到信任。

自 2024 年 7 月 1 日起,DigiCert 品牌 TLS/SSL 证书将使用新的 G2 根体系签发证书,逐步停用旧的 G1 根体系。

1、2024 年 7 月 1 日前,已签发证书不受影响,仍有效直至证书过期,证书有效期内进行重颁发,重颁发的证书仍使用旧根签发;
2、2024 年 7 月 1 日后,提交的 DigiCert 品牌 TLS/SSL 证书新订单将使用新根签发;
3、2024 年 7 月 1 日后, DigiCert 品牌 TLS/SSL 证书多年期订单在下一年续期证书时,将使用新根签发。

moneyslow.com提醒:

1、新的 G2 根体系依然兼容当前主流的操作系统和移动设备,不存在兼容性变化问题,并采用更高安全性的 SHA256 签名算法。
2、如果您在客户端预埋了原根证书或原中级证书,使用新根证书签发的新证书,将出现客户端校验异常,进而引发服务中断等问题。请及时移除预埋操作,改用系统自带的信任库进行验证。
