While having an encrypted key is a good thing for an SSL web server, it just doens't work out so well. When your web server restarts, it hangs during startup asking for a passphrase for all the SSL certs.
To remove the requirement to enter a password you can follow these steps.
First backup you key
# cp www.domain.key www.domain.key.encrypted
Then create a plain text version
# openssl rsa -in www.domain.key -out www.domain.key.plain
Then replace your current key with the new plain text one
# cp www.domain.key.plaintext www.domain.key
Now restart your web server and you shouldn't be prompted for a passphrase.
VERY IMPORTANT!!!!!
You were about to walk away were'nt you?! Well make sure that your
www.domain.key and
www.domain.key.plain files are are owned by
root and are read/write only by root
chmod 600 www.domain.key
