``-o output``
Write to an output file instead of the standard output.
+``-P passphrase``
+ Passphrase to use for the export. If not specified (or specified an empty passphrase), the
+ user is interactively asked to input the passphrase on the terminal. Note that specifying
+ passphrase via -P is insecure, as it can potentially end up in shell history, be visible in
+ ps output, etc.
+
``identity``
The identity name.
