This app will create hidden mailto links for HTML pages, reducing the chances that spam bots can harvest or scrape your email address from your pages.
When using encrypt nothing is obvious.
When un-encrypted, the tag can be edited without having to use this tool to re-generate the entire tag again for each need. While not as secure, it's more flexible for HTML authors.
The non-encrypted version contains 4 data-attributes you can easily modify:
data-u = first half of the email (user)
data-d = second half of email (domain)
data-s = email subject (optional)
data-b = email body (optional)
