ドメインに対する利用権の証明にファイル認証方式を使用する

ファイル認証でTLS/SSLサーバ証明書のドメインに対する利用権を証明します

Use HTTP Practical Demonstration to demonstrate control over a domain on your OV/EV TLS/SSL certificate order. For information about this DCV method and other DCV methods, see Demonstrate control over domains on a pending certificate order.

Validating domains during the certificate order process means certificates can only be issued after you've completed the domain validation. For faster certificate issuance, prevalidate domains when possible. To learn more about domain prevalidation, see Domain prevalidation: Supported DCV methods.

Before you begin

重要

Only use the HTTP Practical Demonstration DCV methods to demonstrate control over fully qualified domain names (FQDNs) exactly as named in the certificate request. To learn more, visit Domain Validation Policy Changes.

Use one of the other supported DCV methods, such as email, DNS TXT, and CNAME, to:

  • Validate wildcard domains (*.example.com).

  • Include subdomains in the validation when validating a higher-level domain. For example, if you want to cover www.example.com, mail.example.com, and one.example.com when validating the higher-level domain example.com.

  • Prevalidate entire domains and subdomains.

To demonstrate control over your domain, host a file containing a DigiCert-generated random value (provided for the domain in your CertCentral account) at a predetermined location on your website: http://{domain-name}/.well-known/pki-validation/fileauth.txt.

After you've created the file and placed it on your site, DigiCert visits the specified URL to confirm the presence of our random value. Make sure to avoid the よくある間違い：ファイル認証DCV方式.

ステップ1：保留中のオーダーのステータスをチェックする

SSL/TLS証明書の［オーダー詳細］ページに移動して、証明書が発行される前に完了する必要があるドメイン検証と組織検証を確認します。

  1. CertCentralアカウントで、オーダーの［オーダー番号］詳細ページにアクセスします。

    1. 左側にあるメインメニューで、［証明書］＞［オーダー］の順に進みます。

    2. ［オーダー］ページの［オーダー番号］列で、証明書のオーダー番号リンクをクリックします。

  2. ［オーダー番号］詳細ページの［認証進行中］セクションで、オーダーの発行ステータスをチェックします（オーダーがドメイン検証または組織検証の完了を待っているかどうか）。

    After validation is complete (domains and organization), the Order status section no longer appears on the Order # details page.

  3. Under You Need To, select the domain's link you want to validate.

  4. In the Prove control over domain window, in the DCV Method dropdown, select HTTP Practical Demonstration.

  5. Create a .txt file and add the DigiCert-provided random value.

    1. Open a text editor (e.g., Notepad).

    2. In the Order token box, copy your token and paste the random value in text editor.

      The random value expires after 30 days.

    3. Save the .txt file under this name: fileauth.txt.

  6. Create the .well-known/pki-validation/ directory on your site.

    For Windows-based servers, the .well-known folder must be created via command line (mkdir .well-known).

  7. Place the fileauth.txt file on your site under .well-known/pki-validation.

    The URL should look something like this:

    http://[yourdomain]/.well-known/pki-validation/fileauth.txt

  8. Complete domain validation

    1. In your CertCentral account, go to the order's Order # details page.

    2. On the Order # details page, in the Validation in Progress section, under You Need To, locate and select the domain link.

    3. In the Prove control over domain window, under 4. Complete domain validation, select Check site.
