Note 3: To convert HMAC HEX code ( signature ) to base64url string. You calculate a keyed-hash message authentication code ( HMAC-SHA) signature using your Secret Access Key (for information about HMAC, go to http://www.rfc-editor.org/rfc/rfc2104.txt) You include the signature and your Access Key ID in the request, and then send the request to AWS. HMAC: Keyed-Hashing for Message Authentication. For signature verification, we'll use the verify Web Crypto method: const result = crypto.subtle.verify(algorithm, key, signature, data); The verifySignature will take in a message as string, signature as a base64 string, and a secret as string. The Request Data contains the Public APP Id, request URI, request content, HTTP method type, timestamp, and nonce by using the Private Secret API Key (this key is not going to be sent in the request). The linked document explains the way the signature needs to be calculated and how to verify it. Compare the calculated in step 1 with the signature payload received. What is rate of emission of heat from a body in space? results in a 400 error with the response body stating the signature is invalid. Since the message is a string and the input data needs to be an ArrayBuffer, we'll once again use a TextEncoder to convert the type. Ignoring bash for a moment, did you read this?
