EmailMunger

Use the EmailMunger gem in your Rails app to encode displayed email addresses on web pages so that they are much less likely to be harvested by bots and bombarded with spam, yet still visible in web browsers. Each character in an email address is converted into its HTML5 UTF-8 character code. Additionally, the '@' and '.' characters are presented in italics. For example, the address abcdefghijklmnopqrstuvwxyz0123456789@example.com becomes &#97;&#98;&#99;&#100;&#101;&#102;&#103;&#104;&#105;&#106;&#107;&#108;&#109;&#110;&#111;&#112;&#113;&#114;&#115;&#116;&#117;&#118;&#119;&#120;&#121;&#122;&#48;&#49;&#50;&#51;&#52;&#53;&#54;&#55;&#56;&#57;<i>&#64;</i>&#101;&#120;&#97;&#109;&#112;&#108;&#101;<i>&#46;</i>&#99;&#111;&#109;

Add this line to your application's Gemfile:

gem 'email_munger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install email_munger

To encode the email address abcdefghijklmnopqrstuvwxyz0123456789@example.com in a Ruby environment, enter the following command: EmailMunger.encode('abcdefghijklmnopqrstuvwxyz0123456789@example.com')

The result is: &#97;&#98;&#99;&#100;&#101;&#102;&#103;&#104;&#105;&#106;&#107;&#108;&#109;&#110;&#111;&#112;&#113;&#114;&#115;&#116;&#117;&#118;&#119;&#120;&#121;&#122;&#48;&#49;&#50;&#51;&#52;&#53;&#54;&#55;&#56;&#57;<i>&#64;</i>&#101;&#120;&#97;&#109;&#112;&#108;&#101;<i>&#46;</i>&#99;&#111;&#109;
