I have a website with a client-side HTML contact form created manually (not as output of an HTML constructor like PHP):
<form action="mailto:firstname.lastname@example.org"> Email Adress:<br> <input type="email" name="email_address" value="" maxlength="100" /> <br> <input type="submit" value="Submit" /> </form>
I desire to hide that
mailto:email@example.com from all HTML source codes that include it, so that users would not be able to find the email address even in source code directly;
This way, generally only customers who have sent me an email and got a reply --- would know the email address (unless the user undid the hiding operation).
Can shell-scripting help hide a destination email address of a client side form, somehow?
