Synopsis
--------

**ndnsec cert-dump** [**-h**] [**-p**] [**-r** [**-H** *host*] [**-P** *port*]]
[**-i**\|\ **-k**\|\ **-f**] *name*

Description
-----------

This command reads an NDN certificate, either from the **Public Information Base (PIB)**
or from the specified file, and prints it on the standard output, either in Base64 encoding
or in a human-readable format.

By default, *name* is interpreted as a certificate name.

Options
-------

.. option:: -i, --identity

   Interpret *name* as an identity name. If specified, the certificate to dump
   is the default certificate of the identity.

.. option:: -k, --key

   Interpret *name* as a key name. If specified, the certificate to dump is the
   default certificate of the key.

.. option:: -f, --file

   Interpret *name* as a path to a file containing the certificate. If *name*
   is "-", the certificate will be read from the standard input.

.. option:: -p, --pretty

   Print the certificate in a human-readable format.
