Encrypted private keys will prevent stunnel from automatic startup,
after a power failure or some other accidential machine reboot.
And even being crypted on the filesystem once decrypted the private key
will stay in memory unencrypted all the time. If someone breaks in the
machine while it is running he/she will get the key from memory not from
The only use of crypted private keys (for deamon-services) I can think
of is that you can prevent someone from stealing your private key if
he/she steals physically the harddisk or the whole machine from your
server-room. And even this has the major disadvantage that the service
will not start without human intervention (the private key's passphrase
input) after unexpected reboots.
