+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 will automatically look 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.
+
+If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module
+(libnsspem.so) needs to be available for this option to work properly.
+
+(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 will use 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
+with libcurl 7.60 or later. 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).
