.SH NAME
|
|
CURLOPT_PROXY_SSLVERSION \- preferred HTTPS proxy TLS version
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLVERSION,
|
|
long version);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long as parameter to control which version of SSL/TLS to attempt to use
|
|
when connecting to an HTTPS proxy.
|
|
|
|
Use one of the available defines for this purpose. The available options are:
|
|
.IP CURL_SSLVERSION_DEFAULT
|
|
The default action. This attempts to figure out the remote SSL protocol
|
|
version.
|
|
.IP CURL_SSLVERSION_TLSv1
|
|
TLSv1.x
|
|
.IP CURL_SSLVERSION_TLSv1_0
|
|
TLSv1.0
|
|
.IP CURL_SSLVERSION_TLSv1_1
|
|
TLSv1.1
|
|
.IP CURL_SSLVERSION_TLSv1_2
|
|
TLSv1.2
|
|
.IP CURL_SSLVERSION_TLSv1_3
|
|
TLSv1.3
|
|
The maximum TLS version can be set by using \fIone\fP of the
|
|
CURL_SSLVERSION_MAX_ macros below. It is also possible to OR \fIone\fP of the
|
|
CURL_SSLVERSION_ macros with \fIone\fP of the CURL_SSLVERSION_MAX_ macros.
|
|
The MAX macros are not supported for WolfSSL.
|
|
.IP CURL_SSLVERSION_MAX_DEFAULT
|
|
The flag defines the maximum supported TLS version as TLSv1.2, or the default
|
|
value from the SSL library.
|
|
(Added in 7.54.0)
|
|
.IP CURL_SSLVERSION_MAX_TLSv1_0
|
|
The flag defines maximum supported TLS version as TLSv1.0.
|
|
(Added in 7.54.0)
|
|
.IP CURL_SSLVERSION_MAX_TLSv1_1
|
|
The flag defines maximum supported TLS version as TLSv1.1.
|
|
(Added in 7.54.0)
|
|
.IP CURL_SSLVERSION_MAX_TLSv1_2
|
|
The flag defines maximum supported TLS version as TLSv1.2.
|
|
(Added in 7.54.0)
|
|
.IP CURL_SSLVERSION_MAX_TLSv1_3
|
|
The flag defines maximum supported TLS version as TLSv1.3.
|
|
(Added in 7.54.0)
|
|
|
|
In versions of curl prior to 7.54 the CURL_SSLVERSION_TLS options were
|
|
documented to allow \fIonly\fP the specified TLS version, but behavior was
|
|
inconsistent depending on the TLS library.
|
|
.SH DEFAULT
|
|
CURL_SSLVERSION_DEFAULT
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
|
|
All TLS backends support this option.
|
|
