This page will help you generate commands to write RFID tags that work with the Creality K2 Plus and CFS. It assumes you already have working knowledge of how to use a PROXMARK3 and have Proxtools by ICEMAN installed.
This page now supports Creality Tag Encryption! You will need the 8 digit UID of the tag to generate the Key for Sector 1. You can even re-use Creality tags and reprogram them with whatever values you want.
WARNING!! I put no safeguards into this page, so you must be careful with the data you enter. There are NO data checks!
You should end up with 3 commands, all with the same number of characters. If you don't, try refreshing the page to get default values and try again.
The number of characters expected for each entry is in paranthesis next to each label

Copying/pasting these might add an additional space at the end - be careful!
