Writing the code to sign data with a private key and verify it with a public key would have been easier to get correct than correctly invoking the JWT library. In fact, the iOS app (which gets this right) doesn’t use a JWT library at all, but manages to verify using a public key in fewer lines of code than the Android app takes to incorrectly use a JWT library!
James Bennett on why Django should not support JWT in core (via) The topic of adding JWT support to Django core comes up occasionally—here’s James Bennett’s detailed argument for not doing that. The short version is that the JWT specification isn’t just difficult to implement securely: it’s fundamentally flawed, which results in things like five implementations in three different languages all manifesting the same vulnerability. Third party modules exist that add JWT support to Django, but baking it into core would act as a form of endorsement and Django’s philosophy has always been to encourage people towards best practices.

Building a stateless API proxy (via) This is a really clever idea. The GitHub API is infuriatingly coarsely grained with its permissions: you often end up having to create a token with way more permissions than you actually need for your project. Thea Flowers proposes running your own proxy in front of their API that adds more finely grained permissions, based on custom encrypted proxy API tokens that use JWT to encode the original API key along with the permissions you want to grant to that particular token (as a list of regular expressions matching paths on the underlying API).
