CBOR + Deterministic serialization!
This is the s**t, finally get rid of Base64 (JOSE) or putting everything crypto-ish in "bstr" (COSE).

Trivial to do, works like charm, and makes ASN.1 DER look like rocket science.

> ABSTRACT: The envelope protocol specifies a format for hierarchical binary data built on CBOR. Envelopes are designed with "smart documents" in mind, and have a number of unique features including easy representation of semantic structures like triples, built-in normalization, a built-in Merkle-like digest tree, and the ability for the holder of a document to selectively encrypt or elide specific parts of a document without invalidating the digest tree or cryptographic signatures that rely on it.
