Sign Java files with Jarsigner using KSP library
Jarsigner is a command-line tool provided as part of the Java Development Kit (JDK). It is used to digitally sign Java Archive (JAR) files and other related artifacts.
Jarsigner and keytool can be used with the DigiCert® Software Trust Manager KSP instead of PKCS11. However, we recommend Jarsigner signing with PKCS11.
Follow these instructions to sign directly using Jarsigner and securely reference your private key stored in Software Trust Manager. Alternatively, integrate Jarsigner with Signing Manager Controller (SMCTL) for simplified signing.
Prerequisites
Windows operating system
Download and configure Windows clients installer
注意
This signing method may not be compatible with other distributions of OpenJDK.
