Appendix F. Using the Keytool

This appendix shows how to use the keytool of the Java 2 Platform SDK. It provides an overview of the keytool's operation, describes the keytool commands, and provides examples of their use.

Overview

The keytool provides the capability to manage a keystore (see Chapter 6,"Key Management and Digital Certificates" ). A keystore is a container for key entries and trusted certificate entries. A key entry consists of a private key and an X.509 certificate chain that authenticates the associated public key. (The keytool does not provide support for symmetric (secret) keys.) A trusted certificate entry is a certificate that authenticates the public key of another party.

The keytool provides the following capabilities:
