CURLOPT_TLSAUTH_TYPE (3) Linux Manual Page

CURLOPT_TLSAUTH_TYPE – set TLS authentication methods

Synopsis

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TLSAUTH_TYPE, long bitmask);

Pass a long as parameter, which is set to a bitmask, to tell libcurl which authentication method(s) you want it to use for TLS authentication.

CURL_TLSAUTH_SRP: TLS-SRP authentication. Secure Remote Password authentication for TLS is defined in RFC5054 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.

CURL_TLSAUTH_NONE (0)

All TLS-based protocols

TODO

You need to build libcurl with GnuTLS or OpenSSL with TLS-SRP support for this to work. Added in 7.21.4

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
