public key and data file?

[riccardobecker]

I have a question or need help

First of all, thanks for your effort to support this and make it public available. I would like to know if there are any testfiles available that I can use and drag and drop in the chargy windows app? Just curious about how this works and how this would work from an EV perspective.

• public key needed?
• data file needed? What is the format of this file?

thanks for your help!

Hi, in e-mobility there are really a lot of data formats. The idea behind Chargy TS was to hide this complexity as good as possible and let the computer - not the user - find the correct data format.

Some vendors use a combined data format containing the transparency data and the public key. This is nice for the usability, but does not always make crypto people very happy (that's why we have an experimental support of signed public keys): https://github.com/OpenChargingCloud/ChargyDesktopApp/tree/master/documentation/chargeIT

Other vendors put the transparency data in one file and the public key into another. Both having well-known file names: https://github.com/OpenChargingCloud/ChargyDesktopApp/tree/master/documentation/ChargePoint

For usability reasons Chargy TS also processes file archives. Then the separation of transparency data and public key(s) is even a plus, as we can include multiple transparency data and have to include the public key only once.
