憑證授權單位 (CA) 無法執行解密操作。當使用進階加密演算法 (如進階加密標準，AES)，但並未設定 CA 使用 CryptoAPI Next Generation (CNG) 金鑰儲存提供者時，就可能發生這個錯誤。如果在憑證註冊時發生這個錯誤，請檢查憑證範本以確定並未啟用金鑰保存的進階加密。

The certification authority (CA) was unable to perform a decryption operation. This error can occur when an advanced encryption algorithm such as Advanced Encryption Standard (AES) is used and the CA has not been configured to use a CryptoAPI Next Generation (CNG) key storage provider. If this error occurred during certificate enrollment, check the certificate template to ensure that advanced encryption for key archival is not enabled.
