Authorization header

To provide credentials for AWS V2 authentication using the Authorization header, you use this format:

Authorization: AWS access-key:signature

In this format:

access-key is the Base64-encoded username for your user account.

signature is a value calculated using your secret key and specific elements of the HS3 request, including the date and time of the request. Your secret key is the MD5-hashed password for your user account.

Because the signature for an HS3 request is based on the request contents, it differs for different requests.

For more information on signatures, see Signatures. For information on changing the password for your user account, see Changing your password.

Here’s an example of an Authorization header for AWS V2 authentication:
