Conflicting <Hash.h> issue

1

Hi guys.

I am trying to compile WebSockets library and Crypto library together with the websocket example code () and I am getting an error like this

.pio\libdeps\d1_mini\WebSockets_ID549\src\WebSockets.cpp:536:77: error: ‘sha1’ was not declared in this scope

If i remove Crypto library, it can compile fine. Does anyone know how to fix this? please advice

platformio.ini

[env:d1_mini]
platform = espressif8266
board = d1_mini
framework = arduino

lib_deps =
# Using library Id
WebSockets
Crypto

Classic name conflict. You should make a fork of the Crypto library and rename its references to Hash.h and the file itself. I wouldn’t know of any other magic fix for this.
