KDM checker

A KDM is an XML file. Its metadata — the composition it unlocks, the validity window, the certificate of the device it was made for and the types of key it carries — is readable plain text. The content keys themselves are encrypted to that device, and this tool neither can nor tries to read them.

Everything happens in your browser. The files are not uploaded, stored or sent anywhere, which matters because KDMs identify your equipment and your bookings.

• The key opens too late. A window that begins after your first show, often because of a time-zone mix-up, means a black screen at showtime.
• The key closes too early. The booking was extended, the key was not. The warning at 48 hours gives you time to ask the distributor.
• The wrong device. Check the target device and serial against the screen you plan to play it on: a key cut for screen 2 will not open on screen 3. See KDM and integrated media block.
