[jira] [Created] (HDDS-15142) Support HMAC-SHA256 trailer signature verification for S3 chunked uploads

             Summary: Support HMAC-SHA256 trailer signature verification for S3 chunked uploads
                 Key: HDDS-15142
                 URL: https://issues.apache.org/jira/browse/HDDS-15142
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Chung En Lee
            Assignee: Chung En Lee


Following the implementation of standard HMAC-SHA256 payload verification, this task extends the functionality to support the STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER algorithm.

When a client uploads a file with trailing checksums (e.g., x-amz-checksum-crc32c), S3G must not close the stream immediately after receiving the 0-byte final chunk. Instead, it must continue to parse the trailing headers and verify the x-amz-trailer-signature to ensure the integrity of the appended checksums.
