This library provides encoding and decoding for the
Concise Binary Object Representation (CBOR) (RFC 7049) serialization format.
It is implemented in pure python with an optional C backend and is compatible
with versions 2.7 through to 3.8. On cPython>=3.3 cbor2 can use a built in C
module for performance similar to how pickle wraps the _pickle C module in the
Python Standard Library.
