base32_pure

Encodes and decodes binary tokens to and from base32.

Description

It uses the Crockford alphabet defined at 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

Usage

require 'base32_pure'

encoded = Base32::Crockford.encode("Some token")
Base32::Crockford.decode(encoded)

hypenated = Base32::Crockford.hypenate(encoded)
Base32::Crockford.decode(hypenated)

Features/problems

The optional check value is not implemented.

Note on Patches/Pull Requests

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
