From 30f1b027c012f8022c67185832fa1aada26c396a Mon Sep 17 00:00:00 2001
From: Werner Koch <wk@gnupg.org>
Date: Fri, 1 Feb 2002 11:39:06 +0000
Subject: * cache.c: Add a few debug outputs.

* protect.c (agent_private_key_type): New.
* agent.h: Add PRIVATE_KEY_ enums.
* findkey.c (agent_key_from_file): Use it to decide whether we
have to unprotect a key.
(unprotect): Cache the passphrase.

* findkey.c (agent_key_from_file,agent_key_available): The key
files do now require a ".key" suffix to make a script's life
easier.
* genkey.c (store_key): Ditto.
