Multiformats is a compliant implementation of `multiformat protocols <https://multiformats.io/>`_:
This is a temporary fork of the original project to be used until the original project incorporates a bug fix to work with newer versions of the 'typing_extensions' dependency. Python versions 3.11 & 3.12 are not tested with this fork.
Bug: https://github.com/hashberg-io/typing-validation/issues/1

Install
-------
You can install the latest release from `PyPI <https://pypi.org/project/multiformats/>`_ as follows:
.. code-block:: console
$ pip install --upgrade multiformats
The following are mandatory dependencies for this module:
- `typing-extensions <https://github.com/python/typing_extensions>`_, for backward compatibility of static typing.
- `typing-validation <https://github.com/hashberg-io/typing-validation>`_, for dynamic typechecking
- `bases <https://github.com/hashberg-io/bases>`_, for implementation of base encodings used by Multibase
The following are optional dependencies for this module:
- `pysha3 <https://github.com/tiran/pysha3>`_, for the ``keccak`` hash functions.
- `blake3 <https://github.com/oconnor663/blake3-py>`_, for the ``blake3`` hash function.
- `pyskein <https://pythonhosted.org/pyskein/>`_, for the ``skein`` hash functions.
- `mmh3 <https://github.com/hajimes/mmh3>`_, for the ``murmur3`` hash functions.
- `pycryptodomex <https://github.com/Legrandin/pycryptodome/>`_, for the ``ripemd-160`` hash function, \
the ``kangarootwelve`` hash function and the ``sha2-512-224``/``sha2-512-256`` hash functions.
You can install the latest release together with all optional dependencies as follows:
.. code-block:: console
$ pip install --upgrade multiformats[full]
Usage
-----
You can import multiformat protocols directly from top level:
>>> from multiformats import *
The above will import the following names:
.. code-block:: python
varint, multicodec, multibase, multihash, multiaddr, CID
The first five are modules implementing the homonymous specifications, while ``CID`` is a class for Content IDentifiers.
Below are some basic usage examples, to get you started: for detailed documentation, see https://multiformats.readthedocs.io/
Varint encode/decode
^^^^^^^^^^^^^^^^^^^^
>>> varint.encode(128)
b'\x80\x01'
>>> varint.decode(b'\x80\x01')
128
Multicodec wrap/unwrap
^^^^^^^^^^^^^^^^^^^^^^
Procedural style:
>>> raw_data = bytes([192, 168, 0, 254])

>>> raw_data.hex()
'c0a800fe'
>>> multicodec_data.hex()
'04c0a800fe'
>>> codec, _raw_data = multicodec.unwrap(multicodec_data)
>>> _raw_data.hex()
'c0a800fe'
>>> codec
Multicodec(name='ip4', tag='multiaddr', code='0x04',
status='permanent', description='')
Object-oriented style:

b'Hello World!'
Object-oriented style:
>>> base32 = multibase.get("base32")
>>> base32.encode(b"Hello World!")
'bjbswy3dpeblw64tmmqqq'
>>> base32.decode('bjbswy3dpeblw64tmmqqq')
b'Hello World!'

>>> digest = sha2_256.digest(data)
>>> digest.hex()
'1220c0535e4be2b79ffd93291305436bf889314e4a3faec05ecffcbb7df31ad9e51a'
Optional truncated digests:
>>> digest = multihash.digest(data, "sha2-256", size=20)
# optional truncated hash size, in bytes ^^^^^^^

'c0535e4be2b79ffd93291305436bf889314e4a3f'
>>> sha2_256.wrap(raw_digest).hex()
'1214c0535e4be2b79ffd93291305436bf889314e4a3f'
CID encode/decode
^^^^^^^^^^^^^^^^^
Decoding from multibase encoded strings:
>>> cid = CID.decode("zb2rhe5P4gXftAwvA4eXQ5HJwsER2owDyS9sKaQRRVQPn93bA")
>>> cid
CID('base58btc', 1, 'raw',
'12206e6ff7950a36187a801613426e858dce686cd7d7e3c0fc42ee0330072d245c95')
>>> cid.base
Multibase(name='base58btc', code='z',
status='default', description='base58 bitcoin')
>>> cid.codec
Multicodec(name='raw', tag='ipld', code='0x55',
status='permanent', description='raw binary')
>>> cid.digest.hex()
'12206e6ff7950a36187a801613426e858dce686cd7d7e3c0fc42ee0330072d245c95'
>>> cid.hashfun
Multicodec(name='sha2-256', tag='multihash', code='0x12',
status='permanent', description='')
>>> cid.raw_digest.hex()
'6e6ff7950a36187a801613426e858dce686cd7d7e3c0fc42ee0330072d245c95'
Multibase encoding:
>>> str(cid) # encode with own multibase 'base58btc'
'zb2rhe5P4gXftAwvA4eXQ5HJwsER2owDyS9sKaQRRVQPn93bA'
>>> cid.encode("base32") # encode with different multibase
'bafkreidon73zkcrwdb5iafqtijxildoonbwnpv7dyd6ef3qdgads2jc4su'
PeerID creation
^^^^^^^^^^^^^^^
Creation of `CIDv1 PeerIDs <https://docs.libp2p.io/concepts/peer-id/>`_:
>>> pk_bytes = bytes.fromhex( # hex-string of 32-byte Ed25519 public key
... "1498b5467a63dffa2dc9d9e069caf075d16fc33fdd4c3b01bfadae6433767d93")
>>> peer_id = CID.peer_id(pk_bytes)
>>> peer_id
CID('base32', 1, 'libp2p-key',
'00201498b5467a63dffa2dc9d9e069caf075d16fc33fdd4c3b01bfadae6433767d93')
#^^ 0x00 = 'identity' multihash used (public key length <= 42)
# ^^ 0x20 = 32-bytes of raw hash digest length
>>> str(peer_id)
'bafzaaiautc2um6td375c3soz4bu4v4dv2fx4gp65jq5qdp5nvzsdg5t5sm'
Multiaddr parse/decode
^^^^^^^^^^^^^^^^^^^^^^
>>> s = '/ip4/127.0.0.1/udp/9090/quic'
>>> multiaddr.parse(s)
Multiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'), Proto('quic'))
>>> b = bytes.fromhex('047f00000191022382cc03')
>>> multiaddr.decode(b)
Multiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'), Proto('quic'))
Multiaddr protocols/addresses
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Accessing multiaddr protocols:
>>> ip4 = multiaddr.proto("ip4")
>>> ip4
Proto("ip4")
>>> udp = multiaddr.proto("udp")
>>> quic = multiaddr.proto("quic")
Creating protocol addresses from human-readable strings:
>>> a = ip4/"192.168.1.1"
>>> a
Addr('ip4', '192.168.1.1')
>>> str(a)
'/ip4/192.168.1.1'
>>> a.value
'192.168.1.1'
>>> bytes(a).hex()
'04c0a80101'
>>> a.value_bytes.hex()
'c0a80101'
Creating protocol addresses from bytestrings:
>>> a = ip4/bytes([192, 168, 1, 1])
>>> a
Addr('ip4', '192.168.1.1')
Multiaddr encapsulation/decapsulation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Creating multiaddresses by protocol encapsulation:
>>> ma = ip4/"127.0.0.1"/udp/9090/quic
>>> ma
Multiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'), Proto('quic'))
>>> str(ma)
'/ip4/127.0.0.1/udp/9090/quic'
Bytes for multiaddrs are computed according to the `(TLV)+ multiaddr format <https://multiformats.io/multiaddr/>`_:
>>> bytes(ip4/"127.0.0.1").hex()
'047f000001'
>>> bytes(udp/9090).hex()
'91022382'
>>> bytes(quic).hex()
'cc03'
>>> bytes(ma).hex()
'047f00000191022382cc03'
Protocol decapsulation by indexing and slicing:
>>> ma[0]
Addr('ip4', '127.0.0.1')
>>> ma[:2]
Multiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'))
>>> ma[1:]
Multiaddr(Addr('udp', '9090'), Proto('quic'))

ip4/\"192.168.1.1\"\n>>> a\nAddr('ip4', '192.168.1.1')\n>>> str(a)\n'/ip4/192.168.1.1'\n>>> a.value\n'192.168.1.1'\n>>> bytes(a).hex()\n'04c0a80101'\n>>> a.value_bytes.hex()\n 'c0a80101'\n\nCreating protocol addresses from bytestrings:\n\n>>> a = ip4/bytes([192, 168, 1, 1])\n>>> a\nAddr('ip4', '192.168.1.1')\n\n\nMultiaddr encapsulation/decapsulation\n^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\nCreating multiaddresses by protocol encapsulation:\n\n>>> ma = ip4/\"127.0.0.1\"/udp/9090/quic\n>>> ma\nMultiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'), Proto('quic'))\n>>> str(ma)\n'/ip4/127.0.0.1/udp/9090/quic'\n\nBytes for multiaddrs are computed according to the `(TLV)+ multiaddr format <https://multiformats.io/multiaddr/>`_:\n\n>>> bytes(ip4/\"127.0.0.1\").hex()\n'047f000001'\n>>> bytes(udp/9090).hex()\n '91022382'\n>>> bytes(quic).hex()\n 'cc03'\n>>> bytes(ma).hex()\n'047f00000191022382cc03'\n\nProtocol decapsulation by indexing and slicing:\n\n>>> ma[0]\nAddr('ip4', '127.0.0.1')\n>>> ma[:2]\nMultiaddr(Addr('ip4', '127.0.0.1'), Addr('udp', '9090'))\n>>> ma[1:]\nMultiaddr(Addr('udp', '9090'), Proto('quic'))\n\n\nAPI\n---\n\nFor the full API documentation, see https://multiformats.readthedocs.io/\n\nThe tables specifying all multicodecs
