Token Verification

You can verify the validity of an encrypted token and retrieve the username by calling the extractUserWithVerify() method.

How to Verify the Encrypted Token

app.get("/verify", async (c) => {
  const token = c.req.query("token");
  const response = await sab.extractUserWithVerify(token);
  if (response.success) {
    return c.json(response);
  } else {
    return c.json(response);
  }
});

If the token is valid, a response like the following will be returned:

{
  "success": true,
  "data": "***********"
}

Internal Behavior of Verification

extractUserWithVerify() checks the following conditions:

• Whether a token is provided
• Whether the token has been tampered with

Authentication is only considered successful if all conditions are met.
