const msgBuffer = new TextEncoder().encode(message);
const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);
const hashArray = Array.from(new Uint8Array(hashBuffer));
const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
return hashHex;
}
Example 3: hmac_sha256 node
let test = crypto.createHmac('sha256', "key").update("json").digest("base64");
