Library for generating IPFS v1 CIDs
Project description
ipfs-cid
A library for building IPFS CID v1 compatible content identifiers using fixed encoding parameters.
Usage
from ipfs_cid import encode_cid_v1
data = b"Hello world"
result = encode_cid_v1(data)
# result is now "bafkreide5semuafsnds3ugrvm6fbwuyw2ijpj43gwjdxemstjkfozi37hq"
Encoding Format
The CID spec supports multiple different encodings and hashing algorithms.
The resulting CID string is composed of the following components:
{multibase prefix} + multibase_encoded({cid version} + {content type} + {multihash})
This library always uses the following encoding parameters:
| multibase | CID version | Content Type | Multihash |
|---|---|---|---|
| base32 | cidv1 | raw | sha2-256 |
More details about the formats below:
Multibase
| encoding | code | description |
|---|---|---|
| base32 | b | rfc4648 case-insensitive - no padding |
Multicodec
| name | code | description |
|---|---|---|
| cidv1 | 0x01 | CID v1 |
| sha2-256 | 0x12 | sha2-256 with 256 bit digest |
| raw | 0x55 | raw binary |
