firmware & application checksum after boot

I'm looking for a way to verify the integrity of my application after boot and before execution on an ESP32 or ESP8266.

One idea is to recurse through the files & libs in the distribution and calculate a checksum, but perhaps there are better ways / more complete mechanism to do so - including firmware & precompiled modules.
