ROT 13 encrypt text to prevent spam

Project description


This package provides a function for ROT 13 encoding text to make it email address displayed on the web harder to automatically harvest by spammers.


This package provides three simple functions:

bud.nospam.rot_13_encrypt('some text')
bud.nospam.js_obfuscated_mailto('','Some Name')

Typically you will pass a string to the js_obfuscated_text() function, and insert the output into a web page. This function will ROT 13 encrypt the text, and embedd it with the necessary Javascript to decrypt the text.

The js_obfuscated_mailto() is a convenience method for wrapping the text in an anchor tag with a mailto: attribute.


This package was inspired by the TextMate ROT13 function, see the original TextMate blog post for further discussion.
