Base62 in Ruby

A simple and fast implementation of base62 in pure Ruby without too much sugar and magic.

It uses character set: 0-9, a-z, A-Z for encoding and decoding.

Base62 is usually used for short URLs.

Add this line to your application's Gemfile:

gem 'base62-rb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install base62-rb

require 'base62-rb'

Base62.encode(3781504209452600)
# => "hjNv8tS3K"

Base62.decode("hjNv8tS3K")
# => 3781504209452600
