Scripts for signing using PKCS11 library on GitHub
Set up DigiCert® Software Trust Manager, client tools and integrate them with GitHub Actions for automation into a CI/CD pipeline.
Prerequisites
GitHub Action build system
Any operating system that supports Java on GitHub Actions
JDK installed on the agent
DigiCert® Software Trust Manager credentials
DigiCert® Software Trust Manager client tools
Client tools
DigiCert® Software Trust Manager clients can be downloaded in a package.
Download client tools
Sign in to DigiCert ONE.
Navigate to DigiCert® Software Trust Manager > Resources > Client tool repository.
Select your operating system.
Click the download icon next to DigiCert® Software Trust Manager 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:
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.
User authentication
Software Trust Manager 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.
Anmerkung
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.
Anmerkung
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 environment variables
Set the following environment variables:
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 GitHub Action
Set certificate file in environment variables
Identify your downloaded client authentication certificate.
Encode the file to base64. For encoding run command:
base64 file_name
In GitHub Secrets add a new repository secret with: Name = SM_CLIENT_CERT_FILE_B64 Value = encoded value from base64 file_name
Setup certificate file for signing using this command:
- name: Setup Certificate run: | echo "${{ secrets.SM_CLIENT_CERT_FILE_B64 }}" | base64 --decode > /d/Certificate_pkcs12.p12 shell: bash
Environment variables setup for GitHub Actions
The client tools need these environment variables to connect with DigiCert® Software Trust Manager. To integrate environment variables as GitHub secrets:
Access GitHub repository
Select Settings
Select Secrets > Actions
Select New repository secret
The values for these environment variables:
Environment variables | Description |
---|---|
SM_CLIENT_CERT_PASSWORD | Password from client authentication certificate setup. |
SM_CLIENT_CERT_FILE_B64 | Base64-encoded text of the certificate, downloaded from client authentication certificate setup. |
SM_HOST | The path to the DigiCert ONE portal with client authorization. AnmerkungIn most cases, this path stays as it is unless you are connecting to a self-hosted instance of the DigiCert ONE product. |
SM_API_KEY | The API token generated during API token setup. |
Command to set environment variables:
- name: Set variables
id: variables
run: |
echo "::set-output name=version::${GITHUB_REF#refs/tags/v}"
echo "::set-output name=KEYPAIR_NAME::github-action-keypair"
echo "SM_HOST=${{ secrets.SM_HOST }}" >> "$GITHUB_ENV"
echo "SM_API_KEY=${{ secrets.SM_API_KEY }}" >> "$GITHUB_ENV"
echo "SM_CLIENT_CERT_FILE=D:\\Certificate_pkcs12.p12" >> "$GITHUB_ENV"
echo "SM_CLIENT_CERT_PASSWORD=${{ secrets.SM_CLIENT_CERT_PASSWORD }}" >> "$GITHUB_ENV"
echo "C:\Program Files\DigiCert\DigiCert One Signing Manager Tools" >> $GITHUB_PATH
shell: bash
Anmerkung
The path for smtools is: "C:\Program Files\DigiCert\DigiCert One Signing Manager Tools".
Create certificate and keypair
Create test keypair and certificate
To generate a RSA test keypair with certificate using GitHub actions:
- name: Generate Test Keypair run: | smctl keypair generate rsa <Keypair Name> --cert-alias=<Certificate Name> --cert-profile-id=<Certificate Profile ID> --generate-cert=true --key-type=TEST shell: cmd
The keypair name and certificate name must be unique, meaning these names cannot already exist on the portal.
To retrieve the certificate profile ID:
Access DigiCert ONE > DigiCert® Software Trust Manager > Certificates > Certificate profiles.
Select a certificate profile to generate the certificate (profile category must be test).
Identify the Profile ID.
Create production keypair with certificate
To generate an RSA production keypair with a given certificate using the GitHub actions pipeline:
- name: Generate Production Keypair run: | smctl keypair generate rsa <Keypair Name> --cert-alias=<Certificate Name> --cert-profile-id=<Certificate Profile ID> --generate-cert=true --key-type=PRODUCTION shell: cmd
The parameters are the same as the previous case, but be sure to select a certificate profile that has the profile category "Production".
Sign
Sign with Jarsigner:
- name: Signing using jarsigner run: | jarsigner -keystore NONE -storepass NONE -storetype PKCS11 -sigalg SHA256withRSA -providerClass sun.security.pkcs11.SunPKCS11 -providerArg pkcs11properties.cfg -signedjar <Path to Output Signed Jar> <Path to the Jar to be Signed> <Keypair Certificate Name/Alias > -tsa http://timestamp.digicert.com shell: cmd
The input parameters for this example are the output path for the signed .jar file, the path to the .jar file to be signed, and the name or alias of the certificate to be used for signing.
Verify signature
Verify with Jarsigner:
- name: Jarsigner verify run: | jarsigner -verify <Path to Signed .jar> shell: cmd
The only input for this command is the path to the signed .jar file that needs to be verified.
