This is a simple JWT authentication API written in Go. It allows users to sign up, sign in, and view their user profile by providing a JWT token in the request headers.

• User sign-up: Users can register by providing an email and password.
• User sign-in: Users can authenticate by providing their registered email and password, and receive a JWT token.
• User profile: Authenticated users can view their user profile by providing the JWT token in the request headers.
