Hi,there.FIRST OF ALL,thanks Ron Eldor for answer my questions via Email.For wider share, I post my last question and his review below.
Now I can run the ECDSA signature on STM32F429 successfully.
Today my problem is that how I can set my private key unchangeable? As far as I concered, the dafault setting is to make the key pair CHANGED everytime. As you can see examples below.BUT I hope my private can be static. Any thoughts?Thanks a lot!
