An implementation of Douglas Crockfords Base32-Encoding in Ruby, with two modifications to make the resulting strings more URL friendly:
- use lower case characters
- use two digits (mod 97-10, ISO 7064) for the checksum
see http://www.crockford.com/wrmg/base32.html
$ gem install base32-url
0.5.0 - use mod 97-10 (ISO 7064) to calculate checksum
0.3.0 - encode into lower case characters, use * ~ _ ^ u for checksum
0.2.0 - added optional checksum
#!/usr/bin/env ruby
require 'base32/url'
Base32::URL.encode(1234) # => "16j"
Base32::URL.encode(100**10, :split=>5, :length=>15) # => "02pqh-ty5nh-h0000"
Base32::URL.decode("2pqh-ty5nh-hoooo") # => 10**100
Base32::URL.encode(1234, checksum: true) # => "16j82"
Base32::URL.decode("16j82", checksum: true) # => 1234
