I see the curl_easy_setopt items CURLOPT_CAINFO (root cert bundle) and
CURLOPT_CAPATH (root cert directory).
I'd like to be able to read them - particularly the default for CAINFO
(CAPATH is documented as NULL) so that they can be passed to the other
library. But the "current" values would be better.
The documentation doesn't list a way to get the values - though they do seem
to show up in debug/verbose output.
Not exactly though. What's shown in the debug/verbose output is the *used*
paths, which can be set by the application so it is not necessarily the
default values you see there.
I'd like to default to Curl's built-in values because it does a good job of
defaulting based on the build system; the others aren't quite as good.
I'm glad you think we're doing a good job there. It's a difficult territory to
maneuver in.
So: Am I missing an API call to get these?
There is none.
If not, perhaps curl_version_info() could provide?
That seems reasonable indeed. You basically want CURL_CA_BUNDLE and
CURL_CA_PATH exposed there, right?
As a side note, in my search I noted that
https://curl.haxx.se/libcurl/c/libcurl.html has a link to
https://curl.haxx.se/libcurl/c/curl-config.html - which wins a 404...
Thanks, Jay subsequently filed that one over at
https://github.com/curl/curl-www/issues/65 and I've landed a fix that should
appear now!
