CURLOPT_TLSAUTH_TYPE(3) Library Functions Manual CURLOPT_TLSAUTH_TYPE(3)
NAME
CURLOPT_TLSAUTH_TYPE - TLS authentication methods
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_TYPE, char *type);
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".
Using this option multiple times makes the last set string override the
previous ones. Set it to NULL to restore to internal default.
The application does not have to keep the string around after setting
this option.
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 CURLOPT_TLSAUTH_USERNAME(3) and
CURLOPT_TLSAUTH_PASSWORD(3) options.
TLS SRP does not work with TLS 1.3.
DEFAULT
blank
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
