The Most Common Java Keytool Keystore Commands

Introduction

Java Keytool is a key and certificate management tool that is used to manipulate Java Keystores, and is included with Java. A Java Keystore is a container for authorization certificates or public key certificates, and is often used by Java-based applications for encryption, authentication, and serving over HTTPS. Its entries are protected by a keystore password. A keystore entry is identified by an alias, and it consists of keys and certificates that form a trust chain.

This cheat sheet-style guide provides a quick reference to keytool commands that are commonly useful when working with Java Keystores. This includes creating and modifying Java Keystores so they can be used with your Java applications.

Note: For easier management of your Java Keystores (using a GUI) check out Portecle.
