Hello,

I’m working on configuring a system and I need some help with setting up ciphering in the crystal.xml file. Can anyone guide me on how to properly configure the ciphering settings within this XML file? Any examples or detailed instructions would be greatly appreciated.

Hi,

crystal.xml doesn't support ciphering. The easiest way is if you read the association view from the meter that supports ciphering and use it.

Hi,

I'm currently working on implementing a DLMS/COSEM library in Node.js, so the specific meter isn't that important to me right now—that's why I'm using a simulator. From what I understand, crystal.xml is just an example of a smart meter setup. Given that, wouldn't it be possible to extend it with XML tags for ciphering, encryption keys, or whatever else is needed for encryption support?

If that's the case, could you provide some details on how to do that?

Thanks!

Hi,

crystal.xml is real meter clone without authentication or encryption.
If you want to add support to ciphering, the best way is to read the meter that supports it. Lots of cipering parameters and classes are missing from the XML, e.g. Security Setup objects.
