[](https://gitter.im/Daegalus/dart-base32?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

Simple base32 encode/decode matching the base32 method used by Google Authenticator.

Features:

• Encodes and Decodes Base32 strings.
• Annotated source code

Getting Started #

Pubspec #

pub.dartlang.org: (you can use 'any' instead of a version if you just want the latest always)

dependencies:
  base32: 1.0.0

import 'package:base32/base32.dart';

Start encoding/decoding ...

// Encode a hex string to base32
base32.encodeHexString('48656c6c6f21deadbeef'); // -> 'JBSWY3DPEHPK3PXP'

// base32 decoding to original string.
base32.decode("JBSWY3DPEHPK3PXP"); // -> '48656c6c6f21deadbeef'

API #

base32.encode(List<int> byteList) #

Generate and return a RFC4122 v1 (timestamp-based) UUID.

• byteList - (List<int>) A list of bytes representing your input.

Returns String representation of the encoded base32.

base32.encodeHexString(String hex) #

Generate and return a RFC4122 v4 UUID.

• hexString - (String) A string of hex values intended to be converted to bytes and encoded.

Returns String representation of the encoded base32

Example: Encode a hex string.

base32.encodeHexString('48656c6c6f21deadbeef'); // -> 'JBSWY3DPEHPK3PXP'

base32.decode(String base32) #

Decodes a base32 string back to its original byte values.

• base32 - (String) The base32 string you wish to decode.

Returns Uint8List of the decoded data.

Example: Decode a base32 string, then output it in hex format

var decoded = base32.decode("JBSWY3DPEHPK3PXP");
var decodedHex = CryptoUtils.bytesToHex(decoded); // -> '48656c6c6f21deadbeef'

Testing #

In dartvm

dart test\base32_test.dart

In Browser

At the moment, this package does not work client-side as it uses server-side only UInt8Lists. I might have to wait till UInt8Arrays and UInt8Lists are merged into 1
