Package Exports
- multihashing
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (multihashing) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
node-multihashing
Use all the functions in multihash.
Wait, why, how is this different from Node
crypto?
This module just makes working with multihashes a bit nicer.
node-multihash is only for
encoding/decoding multihashes, and does not depend on other libs.
This module will depend on various implementations for each hash.
For now, it just uses crypto, but will use sha3 and blake2, etc.
Usage
var multihashing = require('multihashing')
var buf = new Buffer('beep boop')
// by default returns a multihash.
multihashing(buf, 'sha1')
// Use `.digest(...)` if you want only the hash digest.
multihashing.digest(buf, 'sha1')
// Use `.createHash(...)` for a `crypto.createHash` interface.
var h = multihashing.createHash('sha1')
h.update(buf)
h.digest()Examples
