<h1>Task 4: Add the Signing Information to the Request</h1>

<div> 
    After you calculate the signature, you add it to the request. You can add the signing information to a request in one of two ways:
    <ol>
        <li>An HTTP header named Authorization</li>
        <li>The query string</li>
    </ol>
</div>
<div> 
    <strong>Pseudocode showing construction of the Authorization header.</strong>    
    <pre>
    Authorization: algorithm Credential=access key ID/credential scope, SignedHeaders=SignedHeaders, Signature=signature
    </pre>
</div>
<div> 
    <strong>Example of example finished Authorization header. </strong>    
    <pre>
    Authorization: AWS4-HMAC-SHA256 Credential=AKIDEXAMPLE/20150830/us-east-1/iam/aws4_request, SignedHeaders=content-type;host;x-amz-date, Signature=5d672d79c15b13162d9279b0855cfba6789a8edb4c82c400e06b5924a6f2b5d7
