rfc-3548-b32

Implementation of [RFC-3548] Base32 encoding/decoding for node that uses [Buffers] for input/output so it's binary safe.

Installation

npm install rfc-3548-b32 --save

Usage

var base32 = require('rfc-3548-b32');

// Arbitrary binary data:
var bytes = new Buffer([1, 2, 3, 4, 5]);

// bytes (hex): 0102030405
console.log("bytes (hex): %s", bytes.toString('hex'));

// Encode it as base32 string:
var bytesAsBase32 = base32.encode(bytes);

// bytes (b32): AEBAGBAF
console.log("bytes (b32): %s", bytesAsBase32);

// Decode it back to a buffer:
var decodedBytes = base32.decode(bytesAsBase32);

// bytes (hex): 0102030405
console.log("bytes (hex): %s", decodedBytes.toString('hex'));

Functions

$3

Encodes the supplied Buffer in base32. Returns a String.

$3

Decodes the supplied base32 String. Returns a Buffer.

Testing

Tests are in the ./test directory (mocha default). You can run the tests via make:

$ make test

Thanks

Thanks to https://github.com/chrisumbel/thirty-two and https://github.com/OhJeez/thirty-two for the real work in writing the base32 code. This module is just a repackaged version of the latter with the encode return type changed to return a String.
