Reading this it says "We strongly recommend developers to encrypt their key for enhanced security."
Searching around I don't see an easy way to do this and I am no expert in security so I am curious if anyone has a good method to encrypt their licence key in Unity and how would you push the unencrypted key into the right place when Vuforia goes to check the key?
Is it best to get somthing like this?
If someone gets this key how much damage can be done? I mean they can break their version but can they break anything for other users?
