请求证书

本页面介绍了如何在 Certificate Authority Service 中创建证书请求。

您可以使用以下方法请求证书:

  1. 生成您自己的私钥或公钥并提交证书签名 请求 (CSR)。
  2. 使用 CA Service 自动生成的私钥或公钥。
  3. 使用现有的 Cloud Key Management Service (Cloud KMS) 密钥。

准备工作

  1. 为 CA Service 准备好环境

  2. 如需获取颁发证书所需的权限,请联系您的管理员 授权您 CA 服务证书请求者 (roles/privateca.certificateRequester) 或 CA Service Certificate Manager (roles/privateca.certificateManager) IAM 角色。

    如需详细了解 CA Service 的详细信息,请参阅使用 IAM 进行访问权限控制

    如需了解如何向主账号授予 IAM 角色, 请参阅授予单个角色

使用 CSR 请求证书

要获取证书,您需要生成 CSR,然后使用该 CSR 请求证书。

生成 CSR

有关如何使用 OpenSSL 生成 CSR 的详细说明, 请参阅如何使用 OpenSSL 生成 CSR。 在生成配置文件时,您也可以使用以下示例配置文件作为参考。 您的 CSR。

如需使用示例配置文件,请按以下步骤操作:

  1. 使用以下配置创建名为 csr.cnf 的配置文件。

    cat << EOF > csr.cnf
    [req]
    distinguished_name = req_distinguished_name
    req_extensions = v3_req
    prompt = no
    
    [req_distinguished_name]
    CN = example.com
    
    [v3_req]
    keyUsage = critical, digitalSignature, keyEncipherment
    extendedKeyUsage = serverAuth
    subjectAltName = @alt_names
    
    [alt_names]
    DNS.1 = example.com
    DNS.2 = www.example.com
    EOF
    

    此示例生成一个 2048 位 RSA 密钥(密码已加密)和相应的 CSR 包含以下内容:

    • 主题 DN 中的 commonName 属性
    • subjectAlternativeName扩展程序
    • keyUsage 扩展程序(标记为严重)
    • extendedKeyUsage扩展程序

    根据需要修改参数。使用 x509v3_config 配置文件 格式来定义 X.509 证书和 CSR 的扩展,请参阅 OpenSSL 文档

  2. 运行以下 openssl 命令以生成 CSR 和相应的私钥:

    openssl req -newkey rsa:2048 -out csr.pem -keyout key.pem -config csr.cnf
    

    此命令会生成以下文件:

    • csr.pem:您的 CSR,已准备好提交给 CA
    • key.pem:您的私钥,您应妥善保管

    在证书请求中使用 csr.pem 文件。

使用 CSR 提交证书请求

要使用 CSR 请求证书,请按以下步骤操作:

控制台

  1. 转到 Google Cloud 控制台中的 Certificate Authority Service 页面。

    转到 Certificate Authority Service

使用现有的 Cloud KMS 密钥请求证书

您只能使用 Google Cloud CLI 通过 Cloud KMS 密钥请求证书。

gcloud

如需使用 Cloud KMS 密钥创建终端实体服务器 TLS 证书,请执行以下操作: 运行以下命令:

gcloud privateca certificates create \
  --issuer-pool POOL_ID \
  --kms-key-version projects/PROJECT_ID/locations/LOCATION_ID/keyRings/KEY_RING/cryptoKeys/KEY/cryptoKeyVersions/KEY_VERSION \
  --cert-output-file CERT_FILENAME \
  --dns-san "DNS_NAME" \
  --use-preset-profile "leaf_server_tls"

替换以下内容:

  • POOL_ID:CA 池的名称。
  • PROJECT_ID:项目 ID。
  • LOCATION_ID:密钥环的位置。
  • KEY_RING:密钥所在密钥环的名称 。
  • KEY:键的名称。
  • KEY_VERSION:密钥的版本。
  • CERT_FILENAME:PEM 编码格式的路径 证书链文件。证书链文件从最终实体排序 根。
  • DNS_NAME:以英文逗号分隔的 DNS SAN。

从 CA 池中的特定 CA 颁发证书

本部分介绍如何从 CA 池中的特定 CA 颁发证书。

控制台

  1. 转到 Google Cloud 控制台中的 Certificate Authority Service 页面。

    转到 Certificate Authority Service

  2. 点击请求证书

  3. 选择区域。区域必须与 CA 池的区域相同 资源。

  4. 选择 CA 池。

  5. 如需选择 CA,请点击使用此 CA 池中的特定 CA,然后选择 从列表中删除 CA。

  6. 按照使用自动生成的密钥请求证书部分或使用 CSR 请求证书部分的方式选择其他参数 部分。

gcloud

如需定位 CA 池中的特定 CA 以颁发证书,请将 --ca 标志,其中包含必须颁发证书的 CA 的 CA_ID

gcloud privateca certificates create \
  --issuer-pool POOL_ID \
  --ca CA_ID \
  --generate-key \
  --key-output-file KEY_FILENAME \
  --cert-output-file CERT_FILENAME \
  --dns-san "DNS_NAME" \
  --use-preset-profile "leaf_server_tls"

在验证模式下请求证书

在验证模式下请求证书会创建未签名的测试 证书。此测试证书未经过 PEM 编码,不会产生费用。 虽然您无法下载该证书,但是假设证书说明 让您确认自己能够使用所选的 参数。

如需在验证模式下请求证书,请按以下步骤操作:

控制台

  1. 转到 Google Cloud 控制台中的 Certificate Authority Service 页面。

    转到 Certificate Authority Service

  2. 点击请求证书

  3. 选择使用验证模式查看假设的证书说明,而不是签名证书

  4. 请按照请求签名证书的步骤操作。
