クラウドSSL / クラウドSSLワイルドカード

「クラウドSSL」「クラウドSSLワイルドカード」は、3階層または4階層の構造にて有効性が検証される仕様となっており、ルート証明書「USERTrust」対応の中間証明書をインストールする必要があります。

以下の中間証明書をコピーして保存し、サーバーへインストールしてください。

証明書のインストール手順については「証明書のインストール手順」をご参照ください。

■インストール後の階層構造
使用する証明書の発行時期により階層構造が異なります。
証明書の発行日が「2025年8月5日~」の場合
（Sectigo Public Server Authentication Root R46 /
　CloudSecure RSA Domain Validation Secure Server CA 3）
ルート証明書「Sectigo Public Server Authentication」（各クライアント側）
　└ 中間証明書「Sectigo Public Server Authentication Root R46」(サーバー側)
　　└ 中間証明書「CloudSecure RSA Domain Validation Secure Server CA 3」(サーバー側)
　　　　└ お客様取得のSSLサーバ証明書(サーバー側)
証明書の発行日が「~2025年8月4日」の場合
（USERTrust RSA Certification Authority /
　CloudSecure RSA Domain Validation Secure Server CA 2）
ルート証明書「USERTrust」（各クライアント側）
　└ 中間証明書「USERTrust RSA Certification Authority」(サーバー側)
　　└ 中間証明書「CloudSecure RSA Domain Validation Secure Server CA 2」(サーバー側)
　　　　└ お客様取得のSSLサーバ証明書(サーバー側)

中間証明書
