复制 SSL/TLS 证书

所有 DigiCert 证书都可以无限次免费重复颁发。为了增强安全性并简化在多个服务器上安装证书的步骤,请生成新的 CSR 并为每个服务器创建副本证书。


Duplicate certificates require domain and organization validation to be done before you request the certificate. Note that the duplicate certificate process does not include a workflow for validating domains and organizations.

副本证书中的详细信息与原始证书完全相同。副本证书不需要 DigiCert 吊销之前的证书副本。
