# `--proxy-tlsauthtype`

Deprecated option. This has no functionality since 8.22.0.

Set TLS authentication type with HTTPS proxy. The only supported option is
`SRP`, for TLS-SRP (RFC 5054). This option works only if the underlying
libcurl is built with TLS-SRP support.

Equivalent to --tlsauthtype but used in HTTPS proxy context.
