CURLOPTSSLVERIFYHOST

CURLOPTSSLVERIFYHOST is a libcurl option that controls whether libcurl should verify the hostname of the server certificate during an SSL/TLS connection. When this option is set to 0, libcurl will not verify the hostname. When set to 1 (which is the default for most SSL backends), libcurl will check if the hostname in the URL matches the hostname in the server's certificate. This verification is a crucial security measure to prevent man-in-the-middle attacks. If the hostname does not match, the connection will fail. It is generally recommended to keep this option enabled (set to 1) for secure connections. Disabling it by setting it to 0 should only be done in specific, controlled environments where the risks are understood and mitigated, as it significantly weakens the security of the connection. This option is part of libcurl's extensive set of SSL/TLS configuration capabilities.
