Scripts for signing using PKCS11 library on Ant
Prerequisites
Ant installed on the agent
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:
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
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.
Nota
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.
Nota
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. |
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. |
Secure your credentials
Your DigiCert ONE host environment, API key, client authentication certificate, and password make up your environment variables and are required to access DigiCert® KeyLocker client tools. Use one of the methods provided below to securely store your credentials based on your operating system.

An example of an Ant setup that verifies a signed jar:
<property name="jarsigner" value="${env.JAVA_HOME}/bin/jarsigner.exe" />
target name="dist" depends="compile" description="generate the distribution">
<buildnumber />
<!-- Create the distribution directory -->
<mkdir dir="${dist}/lib" />
<!-- Put everything in ${build} into the MyApplication-${version}.${build.number}.jar -->
<jar destfile="${dist}/lib/${jarfilename}" basedir="${build}" />
</target>
<target name="verify" depends="dist" description="verify the jar using jarsigner">
<exec executable="${jarsigner}">
<arg line="-verify ${dist}/lib/${jarfilename}" />
</exec>
</target>Suggerimento
The only input is the path to the signed jar that needs to be verified.
