How does jsonwebtoken.verify work?

jsonwebtoken.verify(token, secretOrPublicKey, [options], callback) is a method in the jsonwebtoken library that is used to verify the validity of a JSON Web Token (JWT). The method takes three arguments: token: The JWT to be verified. secretOrPublicKey: A string or buffer containing either the secret for HMAC algorithms or the PEM encoded public key for RSA and ECDSA. options: An optional object that can contain options for the verification process such as the expected algorithm and issuer. If the verification is successful, the method will return the decoded payload of the token. If the verification fails, the method will throw an error. It's also possible to use a callback function instead of returning a Promise when calling the method by passing in a fourth argument as the callback. The jsonwebtoken library is commonly used in web applications for authentication and authorization purposes.

const jwt = require("jsonwebtoken");

// Example JWT to verify
const token =
  "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c";

// Secret for verifying the JWT
const secret = "mysecretkey";

// Verify the token
jwt.verify(token, secret, (err, decoded) => {
  if (err) {
    console.error(err.message);
  } else {
    console.log(decoded);
  }
});

// Output: { sub: '1234567890', name: 'John Doe', iat: 1516239022 }

In this example, we first define a sample JWT to be verified and a secret key that was used to sign it. We then call jwt.verify method passing in the JWT, the secret key and a callback function. If the JWT is valid, the decoded payload will be logged to the console. Otherwise, an error message will be printed.
