JWT implementation without third party library

i want to implement the JWT in C language, in Texas instrument controller, but i can’t add third party libraries. I have checked the available C sample codes, but all of the jwt implementation uses third-party libraries like openssl/ mbedtls, ect is there any way to implement JWT without using third-party libraries.
Main implementation is HMAC256 function.

any one know please suggest me on this
Thanks Yashvanth

Hi @yashvanth,

Welcome to the Community!

C is not my expertise, but I can help if you have questions about JWTs. What do you want to do with your app? Create and sign JWTs? Verify existing JWT signatures? Have you looked at existing C libraries for inspiration on how to implement?
