'Any' Key support

The any_key feature (which depends on alloc) provides a generic interface for creating and working with any supported key type.

JSON Web Algorithms

This crate provides implementations of the ECDH-ES and ECDH-1PU (draft 4) key agreement operations, for use in deriving a content encryption or key wrapping key. These primitives can be used when producing or consuming JWE envelopes using these algorithms.

no-std

This crate supports the optional alloc feature, gating types and operations that depend on a global allocator. The std feature depends on alloc, and adds support for std::error::Error.
