Scripts for signing using KSP library on Jenkins
Get client tools setup for Jenkins. Integration with Jenkins will allow for automation into a CI/CD pipeline.
Prerequisites
Jenkins build system
Any agent with OS that supports Java on Jenkins
JDK installed on the agent
setup
client for your OS
Signing tools present for the required signing (such as signtool.exe or mage.exe)
Note
You can download client tools from the DigiCert ONE® portal in the > Resources > Client tool repository.
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.
Register the KSP
To register the KSP, open a command prompt and run:
smksp_registrar.exe 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:
smksp_cert_sync.exe
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.
Note
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
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.
Note
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.
Note
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® KeyLocker 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. |
Download required signing tools
Follow the instructions in the articles below to integrate with signing tools.
Note
For more information regarding which file types can be signed with these signing tools, refer to: Integrate third-party signing tools.
Integration with Jenkins
Environment variables setup for pipeline
The client tools need these environment variables to connect with to provide its service. They can be integrated as environment variables that are part of the pipeline as shown in the example below or they can be configured at an OS environment level.
pipeline { environment{ SM_CLIENT_CERT_PASSWORD='**********' SM_CLIENT_CERT_FILE='<Path to client Auth Cert File>' SM_HOST='https://clientauth.one.digicert.com' SM_API_KEY='<Api Token>' } }
Sign
You can sign with Jarsigner, Mage, NuGet, or SignTool.
Sign with SignTool
To sign with SignTool:
stage('sign') { steps { bat 'signtool.exe sign /csp "DigiCert Signing Manager KSP" /kc "KeypairAlias" /f certificate.crt /tr http://timestamp.digicert.com UNSIGNED.EXE' }
The input parameters are the alias of the keypair used for signing, the name/alias of the certificate that needs to be used for signing, and the path to the file that needs to be signed.
Sign with Mage
To sign with Mage:
stage('sign') { steps { bat 'mage -sign deploy.application -CertFile certificate.crt -KeyContainer KeypairAlias -CryptoProvider “DigiCert Signing Manager KSP” ' }
The input parameters are the path to the file that needs to be signed, the name/alias of the certificate that needs to be used for signing, and the alias of the keypair used for signing.
Sign with NuGet
To sign with NuGet:
stage('sign') { steps { bat 'nuget sign HelloWorld.1.3.0.17\* -Timestamper http://timestamp.digicert.com -outputdirectory ..\am-HelloWorld.1.3.0.17 -CertificateFingerprint fe509cdc76517a18a37d927e770216b35683d656 -Verbosity detailed -Overwrite' }
The input parameters are the the path to the file that needs to be signed, the path of the output signed file, and the fingerprint of the certificate that needs to be used for signing.
Sign with Jarsigner
To sign with Jarsigner:
stage('sign') { steps { bat 'jarsigner -keystore NONE -storetype Windows-My -signedjar <signed_file>.jar -sigalg SHA256withRSA -digestalg SHA256 <jarfile> <alias>' }
The input parameters are the path where the signed jar needs to be output, the path to the jar that needs to be signed, and the name/alias of the certificate that needs to be used for signing.
Verify signature
You can verify a signature with Jarsigner, Mage, NuGet, or SignTool.
Verify signature with Jarsigner
To verify a signature with Jarsigner:
stage('verify') { steps { bat 'jarsigner -verify <Path to Signed Jar>' }
Verify signature with Mage
To verify a signature with Mage:
stage('verify') { steps { bat 'mage.exe -verify deploy.application' }
Verify signature with NuGet
To verify a signature with NuGet:
stage('verify') { steps { bat 'nuget verify -All am-HelloWorld.1.3.0.17\*' }
Verify signature with SignTool
To verify a signature with SignTool:
stage('verify') { steps { bat 'signtool.exe sign verify /v /pa UNSIGNED.EXE' }
