.TH CURLOPT_AWS_SIGV4 3 "October 31, 2021" "libcurl 7.83.1" "curl_easy_setopt options"
|
|
|
|
.SH NAME
|
|
CURLOPT_AWS_SIGV4 \- V4 signature
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AWS_SIGV4, char *param);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Provides AWS V4 signature authentication on HTTP(S) header.
|
|
.PP
|
|
Pass a char * that is the collection of specific arguments are used for
|
|
creating outgoing authentication headers.
|
|
The format of the param option is:
|
|
.IP provider1[:provider2[:region[:service]]]
|
|
.IP provider1,\ provider2
|
|
The providers arguments are used for generating some authentication parameters
|
|
such as "Algorithm", "date", "request type" and "signed headers".
|
|
.IP region
|
|
The argument is a geographic area of a resources collection.
|
|
It is extracted from the host name specified in the URL if omitted.
|
|
.IP service
|
|
The argument is a function provided by a cloud.
|
|
It is extracted from the host name specified in the URL if omitted.
|
|
.PP
|
|
NOTE: This call set \fICURLOPT_HTTPAUTH(3)\fP to CURLAUTH_AWS_SIGV4.
|
|
Calling \fICURLOPT_HTTPAUTH(3)\fP with CURLAUTH_AWS_SIGV4 is the same
|
|
as calling this with "aws:amz" in parameter.
|
|
.PP
|
|
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"
|
|
.PP
|
|
If you use just "test", instead of "test:try",
|
|
test will be use for every strings generated
|
|
.SH DEFAULT
|
|
By default, the value of this parameter is NULL.
|
|
Calling \fICURLOPT_HTTPAUTH(3)\fP with CURLAUTH_AWS_SIGV4 is the same
|
|
as calling this with "aws:amz" in parameter.
