CURLOPT_AWS_SIGV4(3)

CURLOPT_AWS_SIGV4(3)       curl_easy_setopt options       CURLOPT_AWS_SIGV4(3)



NAME
       CURLOPT_AWS_SIGV4 - V4 signature

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AWS_SIGV4, char *param);

DESCRIPTION
       Provides AWS V4 signature authentication on HTTP(S) header.

       Pass a char * that is the collection of specific arguments are used for
       creating outgoing authentication headers.   The  format  of  the  param
       option is:

       provider1[:provider2[:region[:service]]]

       provider1, provider2
              The providers arguments are used for generating some authentica‐
              tion parameters such as "Algorithm", "date", "request type"  and
              "signed headers".

       region The argument is a geographic area of a resources collection.  It
              is extracted from the host name specified in the URL if omitted.

       service
              The argument is a function provided by a cloud.  It is extracted
              from the host name specified in the URL if omitted.

       NOTE: This call set CURLOPT_HTTPAUTH(3) to CURLAUTH_AWS_SIGV4.  Calling
       CURLOPT_HTTPAUTH(3) with CURLAUTH_AWS_SIGV4 is the same as calling this
       with "aws:amz" in parameter.

       Example  with "Test:Try", when curl will do the algorithm, it will gen‐
       erate "TEST-HMAC-SHA256"ÄP for "Algorithm",  "x-try-date"  and  "X-Try-
       Date"  for  "date",  "test4_request"  for  "request type", "SignedHead‐
       ers=content-type;host;x-try-date" for "signed headers"

       If you use just "test", instead of "test:try", test  will  be  use  for
       every strings generated

DEFAULT
       By  default,  the  value  of  this  parameter  is  NULL.   Calling CUR‐
       LOPT_HTTPAUTH(3) with CURLAUTH_AWS_SIGV4 is the same  as  calling  this
       with "aws:amz" in parameter.

PROTOCOLS
       HTTP

EXAMPLE
       CURL *curl = curl_easy_init();

       struct curl_slist *list = NULL;

       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL,
                         "https://service.region.example.com/uri");
         curl_easy_setopt(c, CURLOPT_AWS_SIGV4, "provider1:provider2");

         /* service and region also could be set in CURLOPT_AWS_SIGV4 */
         /*
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/uri");
         curl_easy_setopt(c, CURLOPT_AWS_SIGV4,
                          "provider1:provider2:region:service");
         */

         curl_easy_setopt(c, CURLOPT_USERPWD, "MY_ACCESS_KEY:MY_SECRET_KEY");
         curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.75.0

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

NOTES
       This option overrides the other auth types you might have set  in  CUR‐
       LOPT_HTTPAUTH(3)  which  should  be highlighted as this makes this auth
       method special.  This method cannot be combined with other auth types.
