jarsigner:tldr:daf4c
The command you posted is using the "jarsigner" utility in a shell script or command line environment. Here's an explanation of the command structure:
jarsigner ${filename-jar} ${keystore_alias}
-
jarsigner
: This command is used in Java Development Kit (JDK) to sign and verify Java archive (JAR) files. It is mainly used to associate digital certificates with JAR files. -
${filename-jar}
: It is a placeholder for the filename of the JAR file you want to sign. You need to replace${filename-jar}
with the actual JAR file name (including its path if necessary). For example, if your JAR file is named "app.jar", you would replace${filename-jar}
with "app.jar". -
${keystore_alias}
: This is another placeholder for the keystore alias. The keystore is a secure storage where cryptographic keys and their corresponding certificates are stored. You need to replace${keystore_alias}
with the actual alias used for the private key and certificate within the keystore. If you have a keystore with an alias named "myalias", you would replace${keystore_alias}
with "myalias".
After replacing the placeholders with actual values, the command becomes:
jarsigner app.jar myalias
This instructs the "jarsigner" utility to sign the "app.jar" file using the private key and certificate associated with the "myalias" alias in the keystore.
