Is this for a personal project, or commercial?

Posted: Sun Feb 18, 2018 8:47 amOK, that's what I thought. This is personal but same principle would apply for commercial products. Apparently you can use a certificate instead of fingerprint with the updated ESP WiFiClientSecure library. Could the certificate change?
