Intended to provide support for the JOSE suite of IETF (draft)
standards and the closely related JWT (JSON web token) spec
(http://tools.ietf.org/html/draft-ietf-oauth-json-web-token-32/).
Both signed and encrypted JWTs are supported, as well as simple
JWK format keys.
The library is currently intended to support work on an OpenID
Connect implementation and the APIs should not be considered
complete, stable or secure for all use cases.
