CID (Content IDentifier)

What is CID ?
CID is a format for referencing content in distributed information systems,
like IPFS.
It leverages content addressing,
cryptographic hashing, and
self-describing formats.
It is the core identifier used by IPFS and IPLD.
CID is a self-describing content-addressed identifier.
It uses cryptographic hashes to achieve content addressing.
It uses several multiformats to achieve flexible self-description,
namely multihash for hashes,
multicodec for data content
types, and multibase to encode the CID itself into strings.

Sample Usage
>>> from cid import make_cid
>>> make_cid('QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4')
CIDv0(version=0, codec=dag-pb, multihash=b"\x12 \xb9M'\xb9\x93M>\x08\xa5.R\xd7\xda}\xab\xfa\xc4\x84..")

>>> cid = make_cid('QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4')
>>> print(cid.version, cid.codec, cid.multihash)

>>> print(cid.encode())
QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4

>>> str(cid)
'QmaozNR7DZHQK1ZcU9p7QdrshMvXqWK6gpu5rmrkPdT3L4'
