NAME

CURLOPT_PROXY_TLSAUTH_TYPE - set proxy TLS authentication methods

SYNOPSIS

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_TLSAUTH_TYPE, char *type);

DESCRIPTION

Pass a pointer to a zero terminated string as parameter. The string should be the method of the TLS authentication used for the HTTPS connection. Supported method is "SRP".

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_PROXY_TLSAUTH_USERNAME(3) and CURLOPT_PROXY_TLSAUTH_PASSWORD(3) options.
The application does not have to keep the string around after setting this option.

DEFAULT

  ret = curl_easy_perform(curl);
