The Pre-Shared Key (sometimes called shared secret) is basically a form of password for your VPN gateway which is set up on your device. The Pre-Shared Key is specific to your gateway and can be found in your device's configuration guide. VPN Tracker provides setup guides for all major gateway manufacturers. A preshared key can only be configured if this option is set to L2TP IPSec VPN or Automatic. Click to select the Use preshared key for authentication check box. In the Key box, type the preshared key value. This value must match the preshared key value that is entered on the VPN-based server. Click OK two times.

Introduction
Cisco IOS® Software Release 12.3(2)T code introduces the functionality that allows the router to encrypt the ISAKMP pre-shared key in secure type 6 format in nonvolatile RAM (NVRAM). The pre-shared key to be encrypted can be configured either as standard, under an ISAKMP key ring, in aggressive mode, or as the group password under an EzVPN server or client setup. This sample configuration details how to set up encryption of both existing and new pre-shared keys.

Configure
This section presents you with the information you can use to configure the features this document describes.
Note: Use the Command Lookup Tool (registered customers only) to obtain more information on the commands used in this section.
These two new commands are introduced in order to enable pre-shared key encryption:
key config-key password-encryption [master key]
password encryption aes
The [master key] is the password/key used to encrypt all other keys in the router configuration with the use of an Advance Encryption Standard (AES) symmetric cipher. The master key is not stored in the router configuration and cannot be seen or obtained in any way while connected to the router.
Once configured, the master key is used to encrypt any existing or new keys in the router configuration. If the [master key] is not specified on the command line, the router prompts the user to enter the key and to re-enter it for verification. If a key already exists, the user is prompted to enter the old key first. Keys are not encrypted until you issue the password encryption aes command.
The master key can be changed (although this should not be necessary unless the key has become compromised in some way) by issuing the key config-key.. command again with the new [master-key]. Any existing encrypted keys in the router configuration are re-encrypted with the new key.
You can delete the master key when you issue the no key config-key... However, this renders all currently configured keys in the router configuration useless (a warning message displays that details this and confirms the master key deletion). Since the master key no longer exists, the type 6 passwords cannot be unencrypted and used by the router.
Note: For security reasons, neither the removal of the master key, nor the removal of the password encryption aes command unencrypts the passwords in the router configuration. Once passwords are encrypted, they are not unencrypted. Existing encrypted keys in the configuration are still able to be unencrypted provided the master key is not removed.
Additionally, in order to see debug-type messages of password encryption functions, use the password logging command in configuration mode.
