Tells curl to use the specified certificate file to verify the peer. The file
may contain multiple CA certificates. The certificate(s) must be in PEM
format. Normally curl is built to use a default file for this, so this option
is typically used to alter that default file.
curl recognizes the environment variable named 'CURL_CA_BUNDLE' if it is
set, and uses the given path as a path to a CA cert bundle. This option
overrides that variable.
The windows version of curl automatically looks for a CA certs file named
'curl-ca-bundle.crt', either in the same directory as curl.exe, or in the
Current Working Directory, or in any folder along your PATH.
(iOS and macOS only) If curl is built against Secure Transport, then this
option is supported for backward compatibility with other SSL engines, but it
should not be set. If the option is not set, then curl uses the certificates
in the system and user Keychain to verify the peer, which is the preferred
method of verifying the peer's certificate chain.
(Schannel only) This option is supported for Schannel in Windows 7 or later
(added in 7.60.0). This option is supported for backward compatibility with
other SSL engines; instead it is recommended to use Windows' store of root
certificates (the default for Schannel).
