main

public static void main(java.lang.String[] args)

A simple main method for exercising the DepotClient.

 usage: java inca.DepotClient

  -a|--auth     boolean Authenticated (secure) connection?
  -c|--cert     path    Path to the authentication certificate
  -D|--depot    str     Depot specification; host:port
  -h|--help     null    Print help/usage
  -i|--init     path    Path to properties file
  -k|--key      path    Path to the authentication key
  -P|--password str     Specify how to obtain encryption password
  -t|--trusted  path    Path to authentication trusted certificate dir
  -V|--version  null    Display program version
 

Each of these properties, other than --init, can also be specified in the initialization file or in system properties defined via the -D switch. In each of these cases, the configuration name must be prefixed with "inca.depot.", e.g., use "inca.depot.cert" to specify the cert value. Command line arguments override any properties specified in this fashion. main allows the user to communicate with the Depot via a telnet-style interface. Supported values for the --password argument are: "no" or "false" (no encryption); "yes", "true", or "stdin:prompt" (read password from stdin after optionally prompting); "pass:text" (specify the password directly--should only be used for testing and, possibly, in the init file).

Parameters:

args - command line arguments, as above.
