rebus - Generate base64-encoded strings consisting of alphanumeric symbols only.

Project Description

Generate base64-encoded strings consisting of alphanumeric symbols only.

Why did I make this app?

Recently I have been working on implementing of a Google Authenticator app for Plone (which I did for my beloved company - Goldmund, Wyldebeast & Wunderliebe).

For generating of a bar code image, I needed a base32 encoded string. While Android devices could perfectly scan all bar-code image that I would generate, Apple devices would raise errors on bar code images which were generated using strings that contain one or more “=” characters.

The solution found was to add a number of \n at the end of the string to be encoded.

If you happen to experience similar problems, you know what to do.


  • Python 2.6.8+, 2.7.+, 3.3.+


Install latest stable version from PyPI:

$ pip install rebus

…or latest stable version from GitHub:

$ pip install -e git+

…or latest stable version from BitBucket:

$ pip install -e hg+

Usage and examples

Using rebus is damn easy. Whenever you would want to use base64.b32encode or base64.b64encode, replace base64 with rebus.


Required imports

>>> import rebus

b32encode string

>>> rebus.b32encode('abcdefg')

b64encode string

>>> rebus.b64encode('abcdefg')


>>> rebus.urlsafe_b64encode('abcdefg')


It’s possible to decode string, encoded with rebus to their original values.

Required imports

>>> import rebus

b32decode string

>>> rebus.b32decode('MFRGGZDFMZTQUCQK')

b64decode string

>>> rebus.b64decode('YWJjZGVmZwoK')


>>> rebus.urlsafe_b64decode('YWJjZGVmZwoK')
