CURLOPT_SSLVERSION - set preferred TLS/SSL version
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLVERSION, long version);
DESCRIPTION
Pass a long as parameter to control which version of SSL/TLS to attempt to use.
Use one of the available defines for this purpose. The available options are:
CURL_SSLVERSION_DEFAULT
The default action. This will attempt to figure out the remote SSL protocol version.
CURL_SSLVERSION_TLSv1
TLSv1.x
CURL_SSLVERSION_SSLv2
SSLv2
CURL_SSLVERSION_SSLv3
SSLv3
CURL_SSLVERSION_TLSv1_0
TLSv1.0 (Added in 7.34.0)
CURL_SSLVERSION_TLSv1_1
TLSv1.1 (Added in 7.34.0)
CURL_SSLVERSION_TLSv1_2
TLSv1.2 (Added in 7.34.0)
CURL_SSLVERSION_TLSv1_3
TLSv1.3 (Added in 7.52.0)
CURL_SSLVERSION_MAX_DEFAULT
The flag defines maximum supported TLS version as TLSv1.2 or default value from SSL library. Only library NSS currently
allows to get maximum supported TLS version. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_0
The flag defines maximum supported TLS version as TLSv1.0. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_1
The flag defines maximum supported TLS version as TLSv1.1. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_2
The flag defines maximum supported TLS version as TLSv1.2. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_3
The flag defines maximum supported TLS version as TLSv1.3. (Added in 7.54.0)
DEFAULT
CURL_SSLVERSION_DEFAULT
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");
/* ask libcurl to use TLS version 1.1 or later */
curl_easy_setopt(curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1.1 |
CURL_SSLVERSION_MAX_DEFAULT);
/* Perform the request */
curl_easy_perform(curl);
}
AVAILABILITY
SSLv2 is disabled by default since 7.18.1. Other SSL versions availability may vary depending on which backend libcurl has been built to
use.
SSLv3 is disabled by default since 7.39.0.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
