Base 32 (crockford variant) encoding/decoding for JavaScript

This is an implementation of base32 (crockford variant) encoding and decoding for node.js/browser, focused on the browser with 0 dependencies

It's based on base32-browser which is based on base32-js.

What about the n other base32 npm packages?

The purpose of this fork is: it's streamlined for the browser and it actually conforms to crockfords variant.

Getting started

In your shell, install with npm:

npm install base32-crockford-browser

In your code:

var base32 = require('base32-crockford-browser')

// simple api

var encoded = base32.encode('some data to encode')
var decoded = base32.decode(encoded)

Minispec

  • The encoding alphabet consists of the numerals 0-9 and the letters a-z, excluding a few letters that might look like numbers, which we simply interpret as follows:

    • I -> 1
    • L -> 1
    • O -> 0
  • When decoding, capital letters are converted to lowercase and the "ambiguous" letters mentioned above converted to their numeric counterparts.

  • Each character corresponds to 5 bits of input.
  • Lexicographic order of strings is preserved through Base 32 encoding.
