⛔️ DEPRECATED: This module has been superseded by the multiformats module
Use all the functions in multihash.
This module is moving to async/await starting from 0.7.0. The last minor version to support callbacks is 0.6.0, any backports will merged to the branch
callbacks
and released under>0.6.0 <0.7.0
.
This module just makes working with multihashes a bit nicer.
js-multihash is only for
encoding/decoding multihashes, and does not depend on other libs.
This module will depend on various implementations for each hash.
It currently uses crypto
and sha3
in Node.js.
In the browser webcrypto
and browserify-sha3
are used.
$ npm install --save multihashing-async
const multihashing = require('multihashing-async')
The code published to npm that gets loaded on require is in fact a ES5 transpiled version with the right shims added. This means that you can require it and use with your favourite bundler without having to adjust asset management process.
const multihashing = require('multihashing-async')
Loading this module through a script tag will make the multihashing
obj
available in the global namespace.
