{{Short description|Software development tool for security}}

A '''Java KeyStore''' ('''JKS)''') is a [[content repository|repository]] of security certificates,{{spaced ndash}} either [[Authorizationauthorization certificate]]s or [[Publicpublic key certificate]]s{{spaced ndash}} plus corresponding [[Private key|private keys]], - used for instance in [[Transport_Layer_SecurityTransport Layer Security|SSLTLS encryption]].

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

The [[Java Development Kit]] maintains a [[certificate authority|CA]] keystore file named ''cacerts'' in folder ''jre/lib/security''. JDKs provide a tool named ''keytool''<ref>[https://docs.oracle.com/en/java/javase/17/docs/specs/man/keytool.html The ''keytool'' Command - a key and certificate management utility ]</ref> 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,<ref>[http://www.edulib.com/products/keystores-manager/ CERTivity - A multi-platform visual tool for managing keystores]</ref> Portecle<ref>[http://portecle.sourceforge.net Portecle - Portecle is an open-source GUI application for creating, managing and examining keystores.]</ref> and KeyStore Explorer.<ref>[http://keystore-explorer.org KeyStore Explorer - An open source GUI replacement for the Java command-line utilities keytool, jarsigner and jadtool.]</ref>

The [[Java_(programming_language)|Java]] JDK maintains a CAC keystore in jre/lib/security/cacerts. JDKs provide a tool keytool <ref>[http://java.sun.com/javase/6/docs/tooldocs/solaris/keytool.html keytool - Key and Certificate Management Tool]</ref> to manipulate the keystore.
