Introduction
Cisco IOSĀ® 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.

If the PSK (Pre-Shared Key) is too short, or too long, an alert will pop up saying the following: 'The secret must be at least six characters long, no more than 64 characters, and contain four different characters'. 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.
A maximum key length of 48 characters may be generated.Keys may be generated in multiple character or numerical formats including decimal, binary, hexadecimal and octal. Generate up to 4,000,000 unique key combinations and 5,000,000 non-unique key combinations. Encryption can also be performed in your application by including our Encryption DLL into your project. Generate random alpha, numeric, or both, CD keys for software distribution and registration. Fifa 06 cd key generator.
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.
