This quickie post is mainly for my own future benefit… The following is how you perform a pre-shared key recovery on a Cisco ASA. When you configure a PSK on a Cisco ASA and then review the configuration by doing a “show running-config“, all the passwords will be displayed as a bunch of ***’s from then on. There is a publicized, but not well know, way to view the full running-config by doing a “more system:running-config” which will allow you to view the running-config in its entirety. This command is nothing new and has apparently has been around since the PIX days.
