libcurl performs peer SSL certificate verification by default. This is done by using CA cert bundle that the SSL library can use to make sure the peer's server certificate is valid.

If you communicate with HTTPS or FTPS servers using certificates that are signed by CAs present in the bundle, you can be sure that the remote server really is the one it claims to be.

Until 7.18.0, curl bundled a severely outdated ca bundle file that was installed by default. These days, the curl archives include no ca certs at all. You need to get them elsewhere. See below for example.
