comment Is my itsdangerous replacement secure?
How can we know? You haven't said what security guarantees you want to achieve (where are those claims you mention?) nor how you propose to meet those guarantees. Do note that we expect all questions to be self-contained: “go read this web page if you want to understand my question” is not acceptable in a question. You can ask for a review of your code on Code Review; your code must have no known bugs and must be entirely posted in the question.
