Instance Encryption Key

The first time a Percussion CMS instance is started a new AES-GCM 256-bit encryption key unique to the instance is generated in the <InstallDir>/rxconfig/secure/.key location on the server.  This key is then used in all encryption operations going forward.

When the DTS is installed on a web server, different directory, or server than the CMS installation.  The secure directory and it's contents should be copied from:




This ensures that the CMS and DTS are using the same Encryption and can successfully pass encrypted data between the applications.
