You can validate JWT’s using any supporting library - You can see a list on https://jwt.io/. Note: Generating your own JWT is not recommended.

I am trying to create a JWT token with java library by using my own payload and secret and I am able to decode it with java, but when I try to decode it with python I am getting below error.

here is the error that I am getting while decoding from python.
jwt.exceptions.DecodeError: Signature verification failed

By any chance, are you using the library for this issue?

I would suggest testing with another library. As mentioned in the issue, a similar issue was resolved using python-jose.

I am facing similar issue but in node js.
I am trying to verify the jwt token in node js which is generated using java. but it gives JsonWebTokenError: invalid signature error while verifying it.

Thanks,
