The Java Development Kit maintains a CA keystore file named cacerts in folder jre/lib/security. JDKs provide a tool named keytool 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, CERTivity, Portecle and KeyStore Explorer.
- keytool - Key and Certificate Management Tool
