Apologies if I came across belittling your solution. Both are of course equally fine. If you like 
writing C++ code and it works for you, then great! To each one its own.
I just meant to provide an alternate solution a little closer to Protonmail documentation:
https://proton.me/support/download-public-private-key#:~:text=You%20can%20also%20download%20your%20own%20public%20key

(FWIW they suggest using "https://mail-api.proton.me")

Best,
