# UPKI Server Certificate Issuance Service¶

## Basic Information¶

This is a service to issue a server certificate that can be used at uec.ac.jp through the UPKI digital certificate issuing service of the National Institute of Informatics.The issued server certificate can be used for general applications that use TLS (SSL), such as HTTPS.

## 証明書の新規発行・更新手順¶

1. 申請書の提出

Hint

Fill out the UPKI SSL サーバ証明書申請書 in the 情報基盤センター申請書一覧 , and submit it to the Information Technology Center Office (4th floor, East Bldg. 3).Please remember to bring your identification card as we will verify your identity.

For use in research and education:

Both the certificate manager and the application manager on the application form should be .full-time faculty members．

For use in student circle activities, etc.:

The certificate manager’ on the application form can be a student. The application manager should be a full-time faculty member (advisor or administrative staff) who is in a position to supervise the organization.

Based on the application form, the Information Technology Center will confirm the existence of the FQDN (server name) with the domain administrator of the FQDN.After confirming the existence of the certificate, the application will be reviewed and the result will be sent to the UEC account of the certificate manager and the applicant in charge by e-mail.

1. CSR (Certificate Signing Request, 証明書署名要求) の作成

 Attribute Name What to enter C JP ST tokyo L chofu O The University of Electro-Communications CN Server’s FQDN (host name) Email Blank (Specify in the next step.)

Hint

• 2022年7月26日より，主体者DNのOU属性は廃止 されました．主体者DNにOU属性があるCSRは受理されませんので，OU属性はつけないでください

• To enter a blank field in OpenSSL, enter 「.」 (half-width period).

1. TSV の作成

Create a TSV file based on the CSR that you have just created, following the procedure described in 2.2.1.サーバ証明書 in the TSV作成ツール操作マニュアル.

1. Access the TSVツール and click 作成開始.

2. TSVファイルの種別 を次の場合に応じて選択し，この内容で作成開始 を押してください．

新規発行申請用TSV
• サーバ証明書を 新規発行 する場合

• 2022年7月26日以前 に発行され，かつ 主体者DNにOU属性を含む サーバ証明書を 更新 する場合

更新申請用TSV
• 2022年7月27日以降 に発行されたサーバ証明書を 更新 する場合

• 2022年7月26日以前 に発行され，かつ 主体者DNにOU属性を含まない サーバ証明書を 更新 する場合

Hint

サーバ証明書の更新時に入力する 失効対象証明書シリアル番号 は， 10進数値 にしてください．16進数値となっているとエラーとなります．

1. Load the CSR file. In addition, please enter the missing information as follows to create the TSV.

• Although 利用管理者氏名 and 利用管理者所属r are not required, they will be embedded in the body of the mail as the address of the mail sent from the application system, so please enter them as much as possible.

• Please enter only one-byte characters for 利用管理者 Email.

• 利用管理者氏名, 利用管理者所属, Webサーバソフトウェア名等 can be entered in both single-byte and double-byte characters.

• Enter the name of the HTTP server or other software that uses the server certificate in Webサーバソフトウェア名等.

• (オプション) 同一計算機・同一 OS でホスト名が異なる複数のサーバで一つの証明書を利用する 場合, dNSName の項目を以下の例のように指定してください． dNSName=aaa.example.ac.jp,dNSName=bbb.example.ac.jp

1. TSVファイルの送付

1. サーバ証明書と中間CA証明書のダウンロード

Caution

The valid intermediate CA certificate differs depending on whether the server certificate is issued after 19:00 on March 26, 2018 or before 14:00 on March 26, 2018.Please check carefully before use.

1. Install the server certificate (User)

Please follow the サーバー証明書インストールマニュアル to install the server certificate and intermediate CA certificate on your server.After installation, check the expiration date of the server certificate using a browser.

7 (更新時のみ) 古い証明書の失効

サーバ証明書のインストールが完了したら，作業が完了したサーバのFQDNを 情報基盤センターにご連絡ください．TSVファイルの作成は不要です．

## 注意事項¶

### 証明書の更新について¶

After setting up the updated certificate on the server, you need to revoke the old certificate.Please contact the Information Technology Center after completing the replacement of the certificate. It is not necessary to create a TSV file.

Note

When renewing or revoking a server certificate, the 失効対象証明書シリアル番号 should be a decimal value.If the value is a hexadecimal number, an error will occur.

### About the replacement of certificates¶

The Information Technology Center does not provide support for key pair generation or installation of server certificates.Please refer to the web pages of the National Institute of Informatics (NII) and the texts available on the Internet and do the work by yourself.In particular, please be sure to check UPKI電子証明書発行サービス（国立情報学研究所）.

If you want to use an SSL server certificate on a virtual domain server,

• The SSL server certificate issued this time

• The private key (server private key) used to create the TSV file

• Intermediate certificate

Warning

Make sure to delete (cancel) the passphrase of the private key.

### Certificate Expiration Date¶

The validity period of the server certificate is determined by the UPKI digital certificate issuing service of the National Institute of Informatics.Please note that the Information Technology Center will not be able to adjust the deadline.

### Delay or Denial of Certificate Issuance¶

If you set a server name that could be used for phishing as the value of CN or SAN when creating a CSR,the issuance of the certificate will be delayed for legitimacy verification or, in some cases, disallowed.

The audit is conducted by a third-party certification authority.Please note that the Information Technology Center will not be able to provide reasons for delays or denials.

Although the CA does not disclose its criteria, it may delay or deny access to services that may be confused with widely used services such as Google, Microsoft, and Amazon.
