This scenario is for when you have configured a VPN on a Cisco ASA but are unable to remember your Cisco ASA pre-shared-key.

If you’re trying to locate your Cisco ASA pre-shared-key, simply showing the running-configuration from command line or within the ADSM configuration manager will return a masked password (******).

If you have SSH access to the ASA then you can enter:

more system://running-config

From within ADSM click on Tools, Command Line Interface and enter the same command.

The pre-shared-key is now displayed in plain text.

This applies to all versions of Cisco ASA including 5505 and 5510.
