How to include BearSSL

[LordOfDeadbush]

Hello,
I am trying to follow the signing section of the OTA chapter in the documentation, and I can't seem to figure out how to include BearSSL. I was just wondering what the #include was? It doesn't seem to mention this on the docs.

Thank you so much,
Corn

The BearSSL specific C++ classes are defined in BearSSLHelpers.h. But if you just include ArduinoOTA.h, they will be auto-imported, too. A minimal sketch that compiles for a "Pico W" is

#include <Arduino.h>
#include <ArduinoOTA.h>

BearSSL::PublicKey signPubKey(
  "-----BEGIN PUBLIC KEY-----\n"
  "MFswDQYJKoZIhvcNAQEBBQADSgAwRwJAXWRPQyGlEY+SXz8Uslhe+MLjTgWd8lf/\n"
  "nA0hgCm9JFKC1tq1S73cQ9naClNXsMqY7pwPt1bSY8jYRqHHbdoUvwIDAQAB\n"
  "-----END PUBLIC KEY-----\n"
);
BearSSL::HashSHA256 hash;
BearSSL::SigningVerifier sign( &signPubKey );

void setup() {
  Update.installSignature( &hash, &sign );
}

void loop() {
}

Obviously not functional until all the rest is filled in, but it compiles.
