curl built with DarwinSSL doesn't collect server cert

[0golovatyi]

I did this

./buildconfig
./configure --withdarwin-ssl
make
cd docs/examples
make && certinfo

I expected the following

1 certs!
...some cert data here...

curl/libcurl version

built from the latest master (aa73eb4).

macOS 10.14.5

The output I see with running certinfo is 0 certs!

It isn't supported with the Secure Transport backend. Allow me to quote the CURLINFO_CERTINFO man page:

AVAILABILITY

This option is only working in libcurl built with OpenSSL, NSS, Schannel or GSKit support. Schannel support added in 7.50.0

@bagder Thank you for the information.

Is there any other way to collect server cert info in security layer independent way? Seems like now my options are to check CURLINFO_TLS_SSL_PTR, then get a pointer to a backend (openssl, darwinssl, etc.) and use that backend API.

Other than write a patch for curl that brings the certinfo feature to the Secure Transport backend, no.
