CURLOPT_AWS_SIGV4(3)       Library Functions Manual       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  pointer 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 hostname specified in the URL if omitted.

       service
              The argument is a function provided by a cloud. It is  extracted
              from the hostname 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 uses  the  algorithm,  it  generates
       "TEST-HMAC-SHA256"  for  "Algorithm", "x-try-date" and "X-Try-Date" for
       "date",  "test4_request"  for   "request   type",   "SignedHeaders=con‐
       tent-type;host;x-try-date" for "signed headers"

       If  you  use just "test", instead of "test:try", test is used for every
       generated string.

       Setting CURLOPT_HTTPAUTH(3) with the CURLAUTH_AWS_SIGV4 bit set is  the
       same as setting this option with a "aws:amz" parameter.

       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.

DEFAULT
       NULL

PROTOCOLS
       This functionality affects http only

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();

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

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

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


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:

       box; cbp-1 | cbp-1 l | l .  ATTRIBUTE TYPE ATTRIBUTE VALUE = Availabil‐
       ity   web/curl = Stability Uncommitted

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.

       A sha256 checksum of the request payload is used as input to the signa‐
       ture calculation. For POST requests, this is a checksum of the provided
       CURLOPT_POSTFIELDS(3). Otherwise,  it  is  the  checksum  of  an  empty
       buffer.  For requests like PUT, you can provide your own checksum in an
       HTTP header named x-provider2-content-sha256.

       For aws:s3, a x-amz-content-sha256 header is added to every request  if
       not  already present. For s3 requests with unknown payload, this header
       takes the special value "UNSIGNED-PAYLOAD".
