$ npm i @multiformats/sha3
MultihashHashers
s are exported from this library, they produce MultihashDigest
s. Details about these can be found in the multiformats multihash interface definitions.
import * as Block from 'multiformats/block'
import * as codec from '@ipld/dag-cbor'
import { sha3256 as hasher } from '@multiformats/sha3'
async function run () {
const value = { hello: 'world' }
const block = await Block.encode({ value, hasher, codec })
console.log(block.cid)
// -> CID(bafyrmidyqnbqbeh5lmkwavjizfmsz6ezwvjleweh5frwk56akfyugoio2e)
}
run().catch(console.error)
Usage
The @multiformats/sha3
package exports sha3*
, shake*
and keccak*
MultihashHasher
s. The Multicodecs table defines these multihashes.
The following MultihashHasher
s are exported:
sha3224
- SHA3-224sha3256
- SHA3-256sha3384
- SHA3-384sha3512
- SHA3-512shake128
- SHAKE-128 (256 output bits)shake256
- SHAKE-256 (512 output bits)keccak224
- KECCAK-224keccak256
- KECCAK-256keccak384
- KECCAK-384keccak512
- KECCAK-512
e.g. he sha3-384
, multicodec code 0x15
, may be imported as:
import { sha3384 } from '@multiformats/sha3'
