I've test your suggestion, but it didn't work. Results bellow:
$ Enter PEM pass phrase:
FATAL: could not load private key file "server.key": problems getting password
As Tom Laine has explained, the service don't work with encrypted keys
because it would need to ask the administrator for the password (like
above), and would not start until he gives it. The server would need
to keep the clear key in memory for every connection. Anyway, would
still be possible one attacker obtain the key.
