hypercore-id-encoding

Encodes Hypercore keys into z-base32 ids, and decodes both hex/z-base32 strings.

npm install hypercore-id-encoding

Usage

const { encode, decode, normalize } = require('hypercore-id-encoding')

const id = encode(core.key) // (z-base32 String)
const hexEncoded = core.key.toString('hex')

const core = new Hypercore(ram, decode(id)) 
const core2 = new Hypercore(ram, decode(hexEncoded)) // Will also work with hex

const id2 = normalize(id)
const id3 = normalize(hexEncoded)

API

const id = encode(hypercoreKey)

Encodes a 32-byte Hypercore key into a z-base32 id.

hypercoreKey must be a Buffer or an ArrayBuffer.

const buf = decode(hypercoreId)

Decodes an id or pear link into a Hypercore key.

If hypercoreId is a 52-character String, it will be decoded as z-base32.

If hypercoreId is a 64-character String, it will be decoded as hex.

If hypercoreId is already a Buffer and is a valid id, it will be returned as-is.

const id = normalize(any)

Decodes and encodes the input any to always return a z-base32 id.

isValid(any)

Returns a boolean indicating whether the key is a valid hypercore key (meaning that it can be decoded/normalised).
