Scripts for signing using PKCS11 library on GitLab

Set up client tools and integrate them with GitLab for automation into a CI/CD pipeline.

Prerequisites

GitLab build system
Any operating system that supports Java on GitLab
JDK installed on the agent
DigiCert® KeyLocker credentials
DigiCert® KeyLocker client tools

Client tools

DigiCert® KeyLocker clients can be downloaded in a package.

Download client tools

Sign in to DigiCert ONE.
Navigate to DigiCert® KeyLocker > Resources > Client tool repository.
Select your operating system.
Click the download icon next to DigiCert® KeyLocker clients.

Create PKCS11 configuration file

To create a configuration file with the path to this shared library:

Open an integrated development environment (IDE) or plain text editor.

Copy and paste the following text into the editor:

例 1. Windows

name=signingmanager 
library="<path to smpkcs11.dll>"
slotListIndex=0

Sample

name=signingmanager 
library="C:\\Program Files\\DigiCert\\DigiCert Keylocker Tools\\smpkcs11.dll"
slotListIndex=0

例 2. Linux

name=signingmanager 
library="<path to smpkcs11.so>"
slotListIndex=0

Sample:

name=signingmanager 
library="/home/<user>/Keylockertools-linux-x64/smpkcs11.so" 
slotListIndex=0

例 3. macOS

name=signingmanager 
library=<path to smpkcs11.dylib> 
slotListIndex=0

Sample:

name=signingmanager 
library=/Users/<user>/digicert/Keylockertools-mac-x64/smpkcs11.dylib" 
slotListIndex=0

Save the file as pkcs11properties.cfg.
Move the pkcs11properties.cfg file to the same location as the PKCS11 library.

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.

例 4. Windows

You can set the PATH environment variable using command line or via the environment variables.

To set the path to your signing tools via command line:

set PATH=%path%;<path to DigiCert Keylocker Tools>

Command sample:

set PATH=%path%;C:\Program Files\DigiCert\DigiCert Keylocker Tools

To set the path to your signing tools for your system or account:

Search for environment variables in the Windows start menu.
Select Edit environment variables for your account or Edit system environment variables.
Double click on the Path variable.
Click New.
Select Browse.
Select the path to the signing tool.
Click OK to save the path.
Click on OK to close the dialog.

例 5. Linux

To set the path to your signing tools via command line:

Launch the Terminal application.
Open the file in an editor:
```
nano ~/.profile
```

Add any exports definitions you need:

export PATH=<Path to DigiCert Keylocker Tools>

Click CTRL+X to exit.
Click Y to save.
Click Enter to keep the same file name.
Execute the new .profile by restarting Terminal or using:
```
 source ~/.profile
```

例 6. macOS

To set the path to your signing tools via command line:

Launch the Terminal application.
Create a profile file:
```
touch ~/.zprofile
```
Open the file in an editor:
```
open ~/.zprofile
```

Add any exports definitions you need, such as:

export PATH=<Path to DigiCert Keylocker Tools>

To save the new .zprofile, click File > Save (CMD + S).
Close the terminal window and reopen to use new saved variables.

User authentication

DigiCert® KeyLocker enforces multifactor authentication for security. To access keypairs, certificates, and sign code, you need to set up two types of credentials: an API token and an authentication certificate.

Create an API token

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

Follow these steps to generate an API token:

Sign in to DigiCert ONE.
Select the profile icon (top-right).
Select Admin Profile.
Scroll down to API Tokens.
Select  Create API token.
注記
The API token is only shown once, securely store the API key to use it later.

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.

Follow these steps to create a client authentication certificate:

Sign in to DigiCert ONE.
Select the profile icon (top-right).
Select Admin Profile.
Scroll down to Authentication certificates.
Select Create authentication certificate.
注記
The client authentication certificate password shown after creating an client authentication certificate cannot be accessed again, download the certificate and securely store the password to use it later.

DigiCert® Software Trust Managerのセットアップ

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.
PKCS11_CONFIG	Provide the path to the PKCS11 configuration file.
SM_TLS_SKIP_VERIFY	Enter true to disable or false to enable TLS verification on client side.

Integration with GitLab

Environment variables setup for GitLab CI/CD

The client tools need these environment variables to connect with DigiCert® KeyLocker. They can be integrated as GitLab variables in GitLab Repository.

The values for these environment variables:

表 1. Environment variables

Environment variable	Description
SM_CLIENT_CERT_PASSWORD	Password from client authentication certificate setup.
SM_CLIENT_CERT_FILE_B64	Base64-encoded text of the certificate, downloaded from client authentication certificate setup.
SM_HOST	The path to the DigiCert ONE portal with client authorization. 注記 In most cases, this path stays as it is unless you are connecting to a self-hosted instance of the DigiCert ONE product.
SM_API_KEY	The API token generated during API token setup.

Command to set environment variables:

  - set-variables

variables:
  SM_API_KEY: $SM_API_KEY
  SM_CLIENT_CERT_PASSWORD: $SM_CLIENT_CERT_PASSWORD
  SM_HOST: $SM_HOST
  Keypair: 'keypair-GitLab-test'
  SSM: 'C:\Program Files\DigiCert\DigiCert Keylocker Tools'

注記

The path for Keylockertools is: "C:\Program Files\DigiCert\DigiCert Keylocker Tools".

Set certificate file in environment variables

Identify your downloaded client authentication certificate.
Encode the file to base64, using the command:
```
base64 file_name
```
For GitLab variables, go to GitLab > Settings > CI/CD > Variables.
Add the new variable name as "SM_CLIENT_CERT_FILE_B64" and the encoded value from base64 file_name in the "Value" field.

Run this code to setup the 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:  
  - shared-windows
  - windows
  - windows-1809

  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'

Sign

To sign using jarsigner:

stages:
  - Jarsigner-Signing
Jarsigner_signing:
  stage: Jarsigner-Signing
  tags:  
  - shared-windows
  - windows
  - windows-1809

  script:
    - |
      jarsigner -keystore NONE -storepass NONE -storetype PKCS11 -sigalg SHA256withRSA -providerClass sun.security.pkcs11.SunPKCS11 -providerArg %PKCS11_CONFIG% -signedjar <Path to Output Signed Jar> <Path to the Jar to be Signed> <Keypair Certificate Name/Alias > -tsa http://timestamp.digicert.com

The input parameters for this example are:

The output path for the signed .jar file.
The path to the .jar file to be signed.
The name or alias of the certificate to be used for signing.

Verify signature

To verify a signature using jarsigner:

stages:
  - Jarsigner-Verification
Jarsigner_verification:
  stage: Jarsigner-Verification
  tags:  
  - shared-windows
  - windows
  - windows-1809

  script:
    - |
      jarsigner -verify <path to signed .jar file>

The only input for this command is the path to the signed.jar file to be verified.
