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.

Example 1. 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.

Example 2. 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
```

Example 3. 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.
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.

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.
