/**
|
|
* The <code>-cacert</code> keytol command handler is used to import a CA
|
|
* trusted X.509 certificate into a key store.
|
|
* <p>
|
|
* Possible options for this command are:
|
|
* <p>
|
|
* <dl>
|
|
* <dt>-file FILE_NAME</dt>
|
|
* <dd>The fully qualified path of the file containing the trusted CA
|
|
* certificate to import. If omitted, the tool will process STDIN.
|
|
* <p></dd>
|
|
*
|
|
* <dt>-storetype STORE_TYPE</dt>
|
|
* <dd>Use this option to specify the type of the key store to use. The
|
|
* default value, if this option is omitted, is that of the property
|
|
* <code>keystore.type</code> in the security properties file, which is
|
|
* obtained by invoking the {@link java.security.KeyStore#getDefaultType()}
|
|
* static method.
|
|
* <p></dd>
|
|
*
|
|
* <dt>-keystore URL</dt>
|
|
* <dd>Use this option to specify the location of the key store to use.
|
|
* The default value is a file {@link java.net.URL} referencing the file
|
|
* named <code>.keystore</code> located in the path returned by the call to
|
|
* {@link java.lang.System#getProperty(String)} using <code>user.home</code>
|
|
* as argument.
|
|
* <p>
|
|
* If a URL was specified, but was found to be malformed --e.g. missing
|
|
* protocol element-- the tool will attempt to use the URL value as a file-
|
|
* name (with absolute or relative path-name) of a key store --as if the
|
|
* protocol was <code>file:</code>.
|
|
* <p></dd>
|
|
*
|
|
* <dt>-storepass PASSWORD</dt>
|
|
* <dd>Use this option to specify the password protecting the key store. If
|
|
* this option is omitted from the command line, you will be prompted to
|
|
* provide a password.
|
|
* <p></dd>
|
|
*
|
|
* <dt>-provider PROVIDER_CLASS_NAME</dt>
|
|
* <dd>A fully qualified class name of a Security Provider to add to the
|
|
* current list of Security Providers already installed in the JVM in-use.
|
|
* If a provider class is specified with this option, and was successfully
|
|
* added to the runtime --i.e. it was not already installed-- then the tool
|
|
* will attempt to removed this Security Provider before exiting.
|
|
* <p></dd>
|
|
*
|
|
* <dt>-v</dt>
|
|
* <dd>Use this option to enable more verbose output.</dd>
