| .SH NAME |
| CURLOPT_AWS_SIGV4 \- V4 signature |
| .SH SYNOPSIS |
| .nf |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AWS_SIGV4, |
| char *providers_infos); |
| .SH DESCRIPTION |
| provides AWS V4 signature authentication on HTTPS header |
| |
| The provider argument is a string that is merged to some authentication |
| parameters use by the algorithm. |
| It's used by "Algorithm", "date", "request type", "signed headers" arguments, |
| |
| NOTE: This call set CURLOPT_HTTPAUTH to CURLAUTH_AWS_SIGV4. |
| Calling CURLOPT_HTTPAUTH with CURLAUTH_AWS_SIGV4 is the same as calling |
| this with "aws:amz" in paramater. |
| |
| Example with "Test:Try", when curl will do the algorithm, it will Generate: |
| "TEST-HMAC-SHA256" for "Algorithm" |
| "x-try-date" and "X-Try-Date" for "date" |
| "test4_request" for "request type" |
| "SignedHeaders=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 |

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