SSL_CTX_load_verify_locations <https://www.openssl.org/docs/man1.0.2/man3/SSL_CTX_load_verify_locations.html> is required for UWP port to load ca file since OpenSSL will not use the CA of the OS.
But in UWP build, stdio is disabled <https://github.com/openssl/openssl/blob/082c041b4233b17b80129d4ac6b33a28014442b0/Configurations/50-win-onecore.conf#L113> by default. However, SSL_CTX_load_verify_locations relies on the default X509_STORE file lookup functionality uses stdio (via BIO_s_file). That basically means no verification of peers and hosts is possible with OpenSSL on UWP port. Is there a way to fix this or if there's a workaround for UWP ? Thanks, Feng
