* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
--
+http.proxySSLCert::
+ The pathname of a file that stores a client certificate to use to authenticate
+ with an HTTPS proxy. Can be overridden by the `GIT_PROXY_SSL_CERT` environment
+ variable.
+
+http.proxySSLKey::
+ The pathname of a file that stores a private key to use to authenticate with
+ an HTTPS proxy. Can be overridden by the `GIT_PROXY_SSL_KEY` environment
+ variable.
+
+http.proxySSLCertPasswordProtected::
+ Enable Git's password prompt for the proxy SSL certificate. Otherwise OpenSSL
+ will prompt the user, possibly many times, if the certificate or private key
+ is encrypted. Can be overriden by the `GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED`
+ environment variable.
+
+http.proxySSLCAInfo::
+ Pathname to the file containing the certificate bundle that should be used to
+ verify the proxy with when using an HTTPS proxy. Can be overriden by the
+ `GIT_PROXY_SSL_CAINFO` environment variable.
+
http.emptyAuth::
Attempt authentication without seeking a username or password. This
can be used to attempt GSS-Negotiate authentication without specifying
