.SH NAME
CURLOPT_TLSAUTH_USERNAME \- username to use for TLS authentication
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_USERNAME, char *user);
.fi
.SH DESCRIPTION
Pass a char pointer as parameter, which should point to the null\-terminated
username to use for the TLS authentication method specified with the
\fICURLOPT_TLSAUTH_TYPE(3)\fP option. Requires that the \fICURLOPT_TLSAUTH_PASSWORD(3)\fP
option also be set.
The application does not have to keep the string around after setting this
option.
Using this option multiple times makes the last set string override the
previous ones. Set it to NULL to disable its use again.
This feature relies on TLS SRP which does not work with TLS 1.3.
.SH DEFAULT
NULL
.SH PROTOCOLS
This functionality affects 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
Added in curl 7.21.4
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
