How can I verify that JWT is OK?

Answer: This article explains how to verify JSON Web Token. And this article explains the jw.verify() function with sample code.

I tried to read pen file and call verify method. but it always fails.

Could you please confirm if the token is valid if verifying it in https://jwt.io/, and check if the token and the secretOrPublicKey passed to your function are valid?

Also, I found two articles in our community regarding the same error. The details in the articles might help solve the error.

Why does jwt.verify() give "invalid signature"?

In the JWT.io debugger it says it is verified. [testing%20JWT]
