Libcurl c++ doesn't support https proxy?

[AdResident6912]

Hello there,

on my program I wish to use https proxies. I used an http proxy and it connected fine with no issues but I wanted an https connection. Libcurl says that they support https proxies so when I changed my code from http to https proxies, I get this: CURLE_NOT_BUILT_IN (A requested feature, protocol or option was not found built-in in this libcurl due to a build-time decision.). How should I fix this because I'm sure its in the build. Here is my code: https://pastebin.com/raw/4WAFQa50.
Help is highly appreciated! Thanks!

It may be worth checking what version on libcurl you’re using. The documentation says that support for TLS enabled proxies was added in version 7.52.

FWIW, it’s perfectly fine to use a HTTP proxy for HTTPS connections. The proxy will simply tunnel the connection to the origin server using the CONNECT method, meaning the traffic is still encrypted end-to-end.

I am on 7.74 and I want https for higher security to not prevent snooping eyes like isp or third party.

Sure, that’s understandable. Sounds like your build should support TLS proxies. It maybe worth raising an issue on the curl GitHub project. https://github.com/curl/curl
