jwt-cpp isfor creating and validating in C++11 JSON Web Token The header only library.

signature algorithm

jwt-cpp supports all algorithms defined in the standard. The modular design allows for easy addition of other algorithms without any issues.

For completeness, here is a list of all supported algorithms:

overview

There is no hard dependency on the JSON library.Instead, there is ajwt::basic_claimGenerics templated around type traits that describe the semantics of values, objects, arrays, strings, numbers, integers, and booleansJSON typeand methods to convert between them.

jwt::basic_claim<my_favorite_json_library_traits> claim(json::object({{"json", true},{"example", 0}}));

This allows complete freedom in choosing which library to use. For more information,please read this page.

For your convenience, serval traits implementations are provided with some popular JSON libraries. they are:

To maintain compatibility,picojsonis still used to provide a dedicatedjwt::claimalong with all helpers.definitionJWT_DISABLE_PICOJSONThis optional dependency will be removed. Feature defaults from other JSON libraries can be included directly.For more information, seefeature example.

As for base64 requirements for JWTs, this library providesbase.hAll required implementations are provided; however, base64 implementations are very common and have varying degrees of performance.When providing your own base64 implementation, you can defineJWT_DISABLE_BASE64Disable jwt-cpp implementation.
