It's the config register. The "4" means "ignore the config in NVRAM. If you search for "config-register" at www.cisco.com, you'll find a bazillion pages that explain the meaning of each bit. Good luck! | |

enable secret is not encrypted. It's an md5 checksum of the password. Being a one-way function, there is no way to derive the password (unencrypt it) from what is stored on the router.
enable password IS an encrypted password, albeit with a fairly trivial vigenere cipher.
More along the lines of this post, I needed to boot a router (a 2650) without loading the config yesterday. While you could still change the config register using a hex value, it also gave you the option of walking you through a menu that prompted you for the changes you wanted to make. Anyone know how long you've been able to do this? I thought it was pretty nifty.
