问题 So I get different signatures for the same JWT. Header : { "alg": "HS512", "typ": "JWT" } Payload : { "sub": "1234567890", "name": "John Doe", "iat": 1516239022 } as a signing key I used " abc " The resulting JWT from jwt.io is the following: eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.sNgS2IRq0LCvUaIzg9dCBVvmY_9KnrXDEmKTii6U4APbRMeUkU084wf3h5v4baP2WeZOyGunCTEa9wxh25IW6w if I calculate the signature with python like this:
