Sign with jSign

jSign is a open-source code signing tool primarily used to sign Java-related files. jSign is a Java implementation of Microsoft Authenticode that is platform independent and provides an alternative to native tools like signcode and signtool on Windows or the Mono development tools on Unix systems.

Follow these instructions to sign directly using jSign and securely reference your private key stored in DigiCert​​®​​ KeyLocker. Alternatively, integrate jSign with Signing Manager Controller (SMCTL) for simplified signing.


Sign with jSign

The following command can be used to sign on Windows, Linux, or macOS.


jSign uses the same pkcs11configuration.cfg file that is used by the p11tool.


To sign with jSign, use the command:

java -jar <path to jsign> --keystore pkcs11.cfg --storepass changeit --storetype PKCS11 --alias <keypair alias> <unsigned file>

Command sample:

java -jar jsign-5.0.jar --keystore pkcs11.cfg --storepass changeit --storetype PKCS11 --alias keypair1 example.exe

Alternative sign command (Linux only)

To sign with jSign on Linux, use the command:

jsign --keystore pkcs11properties.cfg --storepass NONE --storetype PKCS11 --alias <keypair alias> <unsigned file>

Command sample:

jsign –keystore ./conf/pkcs11properties.cfg –storepass NONE –storetype PKCS11 -alias keytool test.ps1
