Hi all,
is there a benefit to us an external chip like ATECC608A to store crypto keys instead of saving them in the ESP32 flash ?
Will be the performance better? i.e. less RAM % of ESP32 usage, speed...also security of course ?
Thanks
Does your application require secure storage of encryption keys? Does compromise of encryption key causes significant reduction in revenue? Normally, the ATECC608A is used for money-making devices and not necessarily for DIY projects
My questions were general question, regarding performances.
Maybe you save a little bit of RAM. They have a better quality true random number generator. That's about it
If anyone's interested, I have an implementation of the C++ Standard Library for Arduino that includes the <random> header and has all the PRNG engines. You can get it here: GitHub - Michael-Brodsky/PG: Rapid application development tools for avr/samd/megaavr architectures (Arduino, STMicro, Teensy).. You'll need to install the whole library, starting with the root folder pg/ into your sketchbook/libraries folder (where all user libraries go). If you use the green Code button on Github to download a .zip file it'll probably name the root pg-main, but you can change that to just "pg". Hit me up if you need help. Cheers!
