.SH NAME
CURLOPT_TLSAUTH_TYPE \- TLS authentication methods
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_TYPE, char *type);
.fi
.SH DESCRIPTION
Pass a pointer to a null\-terminated string as parameter. The string should be
the method of the TLS authentication. Supported method is "SRP".
.IP SRP
TLS\-SRP authentication. Secure Remote Password authentication for TLS is
defined in RFC 5054 and provides mutual authentication if both sides have a
shared secret. To use TLS\-SRP, you must also set the
\fICURLOPT_TLSAUTH_USERNAME(3)\fP and \fICURLOPT_TLSAUTH_PASSWORD(3)\fP
options.
The application does not have to keep the string around after setting this
option.
TLS SRP does not work with TLS 1.3.
.SH DEFAULT
blank
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
This option works only with the following TLS backends:
GnuTLS and OpenSSL
.SH EXAMPLE
.nf
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_TLSAUTH_TYPE, "SRP");
curl_easy_setopt(curl, CURLOPT_TLSAUTH_USERNAME, "user");
curl_easy_setopt(curl, CURLOPT_TLSAUTH_PASSWORD, "secret");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
.fi
.SH AVAILABILITY
You need to build libcurl with GnuTLS or OpenSSL with TLS\-SRP support for this
to work. Added in 7.21.4
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
