.SH DESCRIPTION
Pass a long set to 1 to enable libcurl's certificate chain info gatherer. With
this enabled, libcurl (if built with OpenSSL, NSS or GSKit) will
extract lots of information and data about the certificates in the certificate
chain used in the SSL connection. This data may then be retrieved after a
transfer using \fIcurl_easy_getinfo(3)\fP and its option
\fICURLINFO_CERTINFO\fP.
