Encodes and decodes binary string or integer tokens to and from base32.

base32_pure

Encodes and decodes binary string or integer tokens to and from base32.

Based on wrimle's base32_pure library

Description

It uses the Crockford alphabet defined at http://www.crockford.com/wrmg/base32.html - which is probably not the most efficient, but it is tolerant to user mistakes.

• It's case insensitive
• I, l and 1 maps to the same value
• 0 and O maps to the same value
• U is excluded to reduce the likelyhood of accidental obscenity

Installation

1. Add the dependency to your shard.yml:
