EHEX files created.Īt this moment 5 people have beta test Lockable Teensy 4.0 boards. Anyone can open this window, create their own key.pem file, and get. Running encrypted programs that way is akin to locking your door but leaving the window open.
Standard Teensy 4.0 made after June 2021 can also run encrypted programs, but the final secure lock mode can't be set. While I haven't written any proper documentation yet, hopefully the info on this window can explain how it's meant to work.
