public final class AwsChunkedDecodingChecksumInputStream
extends AbstractAwsInputStream
                    

Merges chunks from AWS chunked AwsChunkedEncodingInputStream, skipping V4 style signing metadata. The checksum is optionally included in the stream as part of the "trail headers" after the last chunk.

The original stream looks like this:

<pre> 24;chunk-signature=312a41de690364ad6d17629d1e026c448e78abd328f1602276fdd2c3f928d100 ## sample test file ## demo=content 0;chunk-signature=4d2b448448f29b473beb81340f5a3d6c9468e4fbb9ac761cfab63846919011fb x-amz-checksum-sha256:1VcEifAruhjVvjzul4sC0B1EmlUdzqvsp6BP0KSVdTE= </pre>

The format of each chunk of data is:

<pre> [hex-encoded-number-of-bytes-in-chunk];chunk-signature=[sha256-signature][EOL] [payload-bytes-of-this-chunk][EOL] </pre>

The format of the full payload is:

<pre> [hex-encoded-number-of-bytes-in-chunk];chunk-signature=[sha256-signature][EOL] [payload-bytes-of-this-chunk][EOL] 0;chunk-signature=[sha256-signature][EOL] x-amz-checksum-[checksum-algorithm]:[checksum][EOL] [other trail headers] </pre>
