--proxy-ca-native

Tells curl to use the CA store from the native operating system to verify the HTTPS proxy. By default, curl uses a CA store provided in a single file or directory, but when using this option it interfaces the operating system's own vault.

This option works for curl on Windows when built to use OpenSSL, wolfSSL (added in 8.3.0) or GnuTLS (added in 8.5.0). When curl on Windows is built to use Schannel, this feature is implied and curl then only uses the native CA store.
