Keystore View

Open a keystore in your IDE and see what expires next.

Overview

What Keystore View does

Keystore View opens keystore and certificate files inside your JetBrains IDE, so you can check an alias or an expiry date without dropping to keytool or openssl. The viewer is free. Pro adds a project-wide scan for certificates that are expired or expire within 30 days, and export of any certificate chain as PEM.
