CURLOPT_CAPATH(3) curl_easy_setopt options CURLOPT_CAPATH(3) NAME CURLOPT_CAPATH - directory holding CA certificates SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath); DESCRIPTION Pass a char * to a null-terminated string naming a directory holding multiple CA certificates to verify the peer with. If libcurl is built against OpenSSL, the certificate directory must be prepared using the openssl c_rehash utility. This makes sense only when used in combina- tion with the CURLOPT_SSL_VERIFYPEER(3) option. The CURLOPT_CAPATH(3) function apparently does not work in Windows due to some limitation in openssl. The application does not have to keep the string around after setting this option. DEFAULT A default path detected at build time. PROTOCOLS All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. EXAMPLE CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); curl_easy_setopt(curl, CURLOPT_CAPATH, "/etc/cert-dir"); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } AVAILABILITY This option is supported by the OpenSSL, GnuTLS and mbedTLS (since 7.56.0) backends. The NSS backend provides the option only for backward compatibility. RETURN VALUE CURLE_OK if supported; or an error such as: CURLE_NOT_BUILT_IN - Not supported by the SSL backend CURLE_UNKNOWN_OPTION CURLE_OUT_OF_MEMORY ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | web/curl | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO CURLOPT_CAINFO(3), CURLOPT_STDERR(3), CURLOPT_DEBUGFUNCTION(3), NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
