Bs62

Quick and easy Base62 encoder and decoder. The difference between this gem and many others is that it operates on an array of bytes.

Install the gem and add to the application's Gemfile by executing:

$ bundle add bs62

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install bs62

Call encode to encode an array of bytes into Base62:

require "bs62"

bytes = SecureRandom.hex(4).bytes # [99, 56, 97, 54, 57, 101, 54, 97]

Bs62.encode(bytes) # "jY45tzXOpUU"

Similarly, call decode to convert a Base62 string to an array of bytes:

require "bs62"

str = "jY45tzXOpUU"

Bs62.decode(str) # [99, 56, 97, 54, 57, 101, 54, 97]

After checking out the repo, run bin/setup to install dependencies. Then, run rake compile test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and merge that change into main.
