Keystore

A Java KeyStore (JKS) is a repository of security certificates – either authorization certificates or public key certificates – plus corresponding private keys, used for instance in SSL encryption.

In IBM WebSphere Application Server and Oracle WebLogic Server, a file with extension jks serves as keystore.

The Java Development Kit maintains a CA keystore in folder jre/lib/security/cacerts. JDKs provide a tool named keytool[1] to manipulate the keystore. keytool has no functionality to extract the private key out of the keystore, but this is possible with third-party tools like jksExportKey,[2] CERTivity,[3] Portecle[4] and KeyStore Explorer.[5]
