KeyStore Explorer for Mac

Overview — macOS graphical keystore manager

KeyStore Explorer is a free, user-focused application for macOS that provides a graphical interface to manage Java keystores. It removes the need to work directly with command-line utilities (for example, keytool and jarsigner), offering an easier way to handle keys and certificates through a visual workflow.

Main capabilities

• Works with multiple keystore formats, so you can open and maintain different store types.
• Create and export certificates for distribution or backup.
• Generate new key pairs and set up keys for signing or encryption.
• Edit and inspect individual entries inside a keystore with a point-and-click interface.
• Maintain your collection of trusted certificates to control which authorities you accept.
• Sign JAR files using keys stored in the keystore to produce verified Java archives.

Who benefits from this tool

Developers and system administrators who need to manage Java security artifacts but prefer a GUI over a terminal will find this especially useful. It simplifies routine tasks like creating keys, importing certificates, and preparing signed JARs without memorizing command-line arguments.

Quick start guide

1. Install the application on your Mac.
2. Open an existing keystore or create a new one.
3. Add or generate keys and import certificates as needed.
4. Export certificates or use the built-in signing features to sign JARs.
5. Review and update the trusted certificate list to keep your environment secure.

Why use a GUI keystore manager

Using a graphical tool reduces the chance of syntax errors, speeds up repetitive tasks, and provides a clearer view of what’s stored in each keystore entry—making Java key and certificate management more accessible and less error-prone.
