The jarsignature Tool : Introduction « Language « Java Tutorial

The jarsigner tool enables you to sign Java ARchive (JAR) files and verify the signatures of signed JAR files.

The jarsigner tool uses key and certificate information from a keystore to generate digital signatures for JAR files.

A keystore is a database of private keys.

The jarsignature also uses an entity's private key to generate a signature.

The syntax to use the jarsignature tool is:

jarsigner [ options ] jar-file alias
jarsigner -verify [ options ] jar-file
