Cisco ASA Pre-shared Key Recovery

If you are responsible for any device running Cisco ASA OS and make use of pre-shared-keys with VPN tunnels, there will come a time when you will need access to those VPN keys.

There are two ways to get the pre-shared-keys from running-config, first the local version:

asa# more system:running-config

This will output the running-config with the pre-shared-keys in plain text.

The second method and the one that should be setup in most cases. Recovery pre-shared-key from TFTP backup of the Cisco ASA configuration. Check the running-config for something similar to the following:

asa(config-archive)#path tftp://$h

The backup configs on the auto archive TFTP server will be in plain text.
