cipher.getAuthTag() Method

cipher.getAuthTag() Method is a Node.js topic. In plain words you use it for login token in protected /admin. Don’t start with a slogan — start with that picture.

Smallest example: verify token in middleware. Type it, run it, and say what you see. If you can do that from memory, you know cipher.getAuthTag() Method.

From the example next to this theory — cipher.getAuthTag() Method: find user 2, then list names. Say both prints..

Trap — storing JWT in localStorage as the only plan. Fix that before you talk about advanced Node.js.

Viva — what is cipher.getAuthTag() Method? Then show verify token in middleware. Then name the trap.

Exam tip

What is cipher.getAuthTag() Method? Show this: verify token in middleware. Trap: storing JWT in localStorage as the only plan.

Example

// cipher.getAuthTag() Method
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

cipher.getAuthTag() Method: find user 2, then list names. Say both prints.
