Construct a String To Sign
Construct a String to Sign from request elements
string_to_sign( algorithm = "AWS4-HMAC-SHA256", datetime, region, service, request_hash )
algorithm |
A character string containing the hashing algorithm used in signing process. Should only be “AWS4-HMAC-SHA256”. |
datetime |
A character string containing a UTC date in the form of “YYYYMMDDTHHMMSSZ”. |
region |
A character string containing the AWS region for the request. |
service |
A character string containing the AWS service (e.g., “iam”, “host”, “ec2”). |
request_hash |
A character string containing the hash of the canonical request, perhaps as returned by |
This is a mostly internal function that creates a “String To Sign”, which is part of the Signature Version 4. Users probably only need to use the signature_v4_auth function to generate signatures.
