GitLab Software Trust Manager (STM) 統合 -KSP

前提条件

  • DigiCert​​®​​ Software Trust Managerのセットアップ

  • DigiCert​​®​​ KeyLocker credentials

  • DigiCert​​®​​ KeyLocker client tools

Client tools

DigiCert​​®​​ KeyLocker clients can be downloaded in a package.

Download Client tools

  1. Sign in to DigiCert ONE.

  2. Navigate to DigiCert​​®​​ KeyLocker > Resources > Client tool repository.

  3. Select your operating system.

  4. Click the download icon next to DigiCert​​®​​ KeyLocker clients.

Register the KSP

To register the KSP, open a command prompt and run:

smctl windows ksp register

Verify the KSP

To verify that your KSP is configured properly, and that your client can properly authenticate to the DigiCert​​®​​ KeyLocker service, run:

certutil.exe -csp "DigiCert Software Trust Manager KSP" -key -user

Synchronize certificates

For the client tools to access the private keys in the service through the Key Storage Provider (KSP), your certificates must be synchronized to the local certificate store. Only if the certificate is synchronized, the private key remains stored securely in DigiCert​​®​​ KeyLocker.

To synchronize your certificates to the local certificate store, open a command prompt and run:

smctl windows certsync

To view the certificates, open Certificate Manager for the user account used to run the certificate sync utility:

certmgr.msc

If you do not see your certificates in the Certificate Manager, verify that you have opened the correct certificate store. There is a different certificate store for each Windows user account.

注記

All certificates are synched to the user store only. The certificates are not synchronized to the machine store (yet).

Set PATH environment variables

Operating systems use the environment variable called PATH to determine where executable files are stored on your system. Use the PATH environment variable to store the file path to your signing tools to ensure that the CLI can reference these signing tools.

User authentication

KeyLocker enforces multi-factor authentication for security purposes. To access keypairs, certificates, and sign code, you need to set up two types of credentials: An API key and an authentication certificate.

Create an API key

The API key is an authentication method used to verify you as a user and your permissions assigned in DigiCert ONE. The API key provides the first factor authentication.

  1. In DigiCert ONE, select the profile (profile_icon.png) icon, and then select Admin Profile.

  2. Under API keys, select Create API key.

  3. For Name, enter a descriptive name for the key.

  4. For End date (optional), enter the date when the key should expire.

  5. Select Create. The API key appears this one time and can't be accessed again. Securely store the API key for future use.

Create an authentication certificate

The client authentication certificate is an authentication method used to verify you as a user and your permissions assigned in DigiCert ONE. The client authentication certificate provides the second factor authentication.

  1. In DigiCert ONE, select the profile (profile_icon.png) icon, and then select Admin Profile.

  2. Under Client authentication certificates, select Create client authentication certificate.

  3. For Nickname, enter a descriptive name for the key.

  4. For End date, enter the date when the certificate should expire.

  5. Select the desired Encryption and Signature hash algorithm.

  6. Select Generate certificate. The password appears this one time and can't be accessed again. Download the certificate and securely store the password for future use.

システム変数として設定することで、環境変数が永続的に残るようにしてください。

Variable

Description

SM_API_KEY

Provide your API token.

SM_CLIENT_CERT_FILE

Provide your client authentication certificate.

SM_CLIENT_CERT_PASSWORD

Provide your client certificate password.

SM_HOST

Provide your host environment.

Set certificate file in environment variables

  1. Identify your client authentication certificate.

  2. Encode the file to base64. For encoding run command:

    base64 file_name

  3. In GitLab > CI/CD Settings > Variables add the new variables:

    Key = SM_CLIENT_CERT_FILE_B64
Value = encoded value from base64 file_name

  4. Setup certificate file for signing:

    stages:
  - set-SM-certificate

variables:
  SM_API_KEY: $SM_API_KEY
  SM_CLIENT_CERT_PASSWORD: $SM_CLIENT_CERT_PASSWORD
  SM_HOST: $SM_HOST

set_SM_certificate:
  stage: set-SM-certificate
  tags:  
  - saas-windows-medium-amd64

  script:
    - |
      cd C:\
      New-Item C:\CERT_FILE.p12.b64
      Set-Content -Path C:\CERT_FILE.p12.b64 -Value $SM_CLIENT_CERT_FILE_B64
      certutil -decode CERT_FILE.p12.b64 Certificate_pkcs12.p12

  variables:
    SM_CLIENT_CERT_FILE: 'C:\Certificate_pkcs12.p12'

Software Trust Managerのセットアップ

クライアントツールがDigiCert​​®​​ Software Trust Managerと接続するためには、これらの環境変数が必要です。

これらは　GitLab RepositoryのGitLab 変数として統合することができます。

これらの環境変数に設定する値は、以下のようになります。

表 1. 環境変数

環境変数

説明

SM_CLIENT_CERT_PASSWORD

パスワードは、クライアント認証用証明書の設定により取得されたパスワードです。

SM_CLIENT_CERT_FILE_B64

クライアント認証用証明書の設定からダウンロードした証明書を base64 でエンコードしたテキスト。

SM_HOST

クライアント認証のある、DigiCert Oneポータルへのパス。

注記

DigiCert ONE 製品のセルフホスト型インスタンスに接続しない限り、ほとんどの場合、このパスはそのまま残ります。

SM_API_KEY

APIトークン設定中に生成されるAPIトークン。

SM_CODE_SIGNING_CERT_SHA1_HASH

環境変数を設定するコマンド:

stages:
  - set-variables

variables:
  SM_API_KEY: $SM_API_KEY
  SM_CLIENT_CERT_PASSWORD: $SM_CLIENT_CERT_PASSWORD
  SM_HOST: $SM_HOST
  SIGNTOOL: 'C:\Program Files (x86)\Windows Kits\10\App Certification Kit\signtool.exe'
  MAGE: 'C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\mage.exe'
  SSM: 'C:\Program Files\DigiCert\DigiCert ONE Signing Manager Tools'

注記

"C:\Program Files (x86)\Windows Kits\10\App Certification Kit" は、signtool.exeのパスであり、"C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools" は、mage.exeのパスです。

クライアントツールの設定

クライアントコントロールのセットアップ

GitLab CI/CD からクライアントコントロールを起動するために、以下の curl コマンドで smtools-Windows-x64.msI　をダウンロードしてインストールします。

stages:
  - set-SM-certificate

set_SM_certificate:
  stage: set-SM-certificate
  tags:  
  - saas-windows-medium-amd64
