HMAC-SHA Signatures<br />
Required Authentication Information<br />
When accessing Amazon SQS using the Query API, you must provide the following items so the request<br />
can be authenticated:<br />
• AWS Access Key ID—Your AWS account is identified by your Access Key ID, which AWS uses to<br />
look up your Secret Access Key.<br />
• Signature—Each request must contain a valid HMAC-SHA request signature, or the request is rejected.<br />
You calculate the request signature by using your Secret Access Key, which is a shared secret known<br />
only to you and AWS.<br />
• Date—Each request must contain the time stamp of the request. You can provide an expiration date<br />
and time for the request instead of or in addition to the time stamp.<br />

Secret Access Key. For more information about those, see Your AWS Account (p. 18) and Your AWS<br />
Identifiers (p. 18).<br />
