SHA resource no longer correct for ESP32

[TheMadTexan42]

Can no longer build on ESP32 due to a change in the ESP32 SHA libraries.

hwcrypto/sha.h no longer exists.

The workaround seems to be to replace
#include <hwcrypto/sha.h>
in
\WebSockets.cpp (line42)
by
#include <esp32/sha.h>

(see espressif/esp-idf#3245)

However this is a recent change so ultimately it depends on the toolchain version you have in place for the ESP

#warning esp32/sha.h is deprecated, please use sha_parallel_engine.h instead

[JonLevin25]

Is there a way to #define <hwcrypto/sha.h> <esp32/sha.h> from user code, to avoid changing library?

The preprocessor doesn't seem to like it

In file included from src/main.cpp:5:
src/remote_debug.h:31:9: error: macro names must be identifiers
 #define <hwcrypto/sha.h> <esp32/sha.h>

here is a good patch

Links2004/arduinoWebSockets#738 (comment)

  #if ESP_IDF_VERSION_MAJOR >= 4
    #if ( ESP_ARDUINO_VERSION >= ESP_ARDUINO_VERSION_VAL(1, 0, 6) )
      #include "sha/sha_parallel_engine.h"
    #else
      #include <esp32/sha.h>
    #endif  
  #else
    #include <hwcrypto/sha.h>
  #endif
