Secure store is a technology designed used to enable a more fail-safe means of storing sensitive license content on a user's machine.

Traditionally, a single file location or registry key is used within applications to store information such as usage counters, trial information and other client-specific content. Conversely, secure store works similarly to a virtual file system, by encrypting the content and then duplicating it to provide redundancy.

Within LM-X, secure store is used with borrow, grace , and and trial licenses and for client store.

For maximum flexibility and safety, secure store technology is designed to be used per user, i.e. by the currently logged-in user of the machine.

Note that secure store might not migrate successfully from an older version of LM-X to a newer version. For example, if you use LMX_ClientStoreSave with an older LM-X version and then attempt to use LMX_ClientStoreLoad on the same variable with a newer LM-X version, you may get the error LMX_FILE_READ_ERROR. 

Note: Upon first compilation of the LM-X SDK, the LM-X security configuration file (security_config.lmx) is automatically created in the config directory. This file holds various security-related parameters, and is used to create license files and embed the security configuration into the license server and client libraries.
