There are three different kinds of "certificates" to keep track of when we
talk about using SSL-based protocols (HTTPS or FTPS) using curl or libcurl.
- - Client certificate. The server you communicate may require that you can
- provide this in order to prove that you actually are who you claim to be.
- If the server doesn't require this, you don't need a client certificate.
-
- A client certificate is always used together with a private key, and the
- private key has a pass phrase that protects it.
-
- - Server certificate. The server you communicate with has a server
- certificate. You can and should verify this certificate to make sure that
- you are truly talking to the real server and not a server impersonating
- it.
-
- - Certificate Authority certificate ("CA cert"). You often have several CA
- certs in a CA cert bundle that can be used to verify a server certificate
- that was signed by one of the authorities in the bundle. curl does not
- come with a CA cert bundle but most curl installs provide one. You can
- also override the default.

- The server certificate verification process is made by using a Certificate
