Long: proxy-ssl-auto-client-cert
Help: Use auto client certificate for proxy (Schannel)
Added: 7.77.0

Same as --ssl-auto-client-cert but used in HTTPS proxy context.
schannel: Disable auto credentials; add an option to enable it - Disable auto credentials by default. This is a breaking change for clients that are using it, wittingly or not. - New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl to automatically locate and use a client certificate for authentication, when requested by the server. - New curl tool options --ssl-auto-client-cert and --proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT. This option is only supported for Schannel (the native Windows SSL library). Prior to this change Schannel would, with no notification to the client, attempt to locate a client certificate and send it to the server, when requested by the server. Since the server can request any certificate that supports client authentication in the OS certificate store it could be a privacy violation and unexpected.
