About:
KeyStore Explorer is a graphical user interface (GUI) tool designed to manage Java keystores, certificates, and private keys.

The tool supports various keystore formats including JKS, PKCS12, and BKS.
Key Features:
  • Graphical interface for keytool and jarsigner operations
  • Support for multiple keystore formats (JKS, PKCS12, BKS, JCEKS, BKS, UBER)
  • Certificate chain visualization and management
  • Drag and drop functionality for keystore entries
  • Built-in key and certificate generation wizards
Use Cases:
