# `--proxy-cert`

Use the specified client certificate file when communicating with an HTTPS
proxy. The certificate must be in PKCS#12 format if using Secure Transport, or
PEM format if using any other engine. If the optional password is not
specified, it is queried for on the terminal. Use --proxy-key to provide the
private key.

This option is the equivalent to --cert but used in HTTPS proxy context.
