The Base64 module provides for the encoding (
#urlsafe_encode64) and decoding (
#urlsafe_decode64) of binary data using a Base64 representation.
Add this line to your application's Gemfile:
And then execute:
$ bundle install
Or install it yourself as:
$ gem install base64
A simple encoding and decoding.
require "base64" enc = Base64.encode64('Send reinforcements') # -> "U2VuZCByZWluZm9yY2VtZW50cw==\n" plain = Base64.decode64(enc) # -> "Send reinforcements"
The purpose of using base64 to encode data is that it translates any binary data into purely printable characters.
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake 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 then run
bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the
.gem file to rubygems.org.
