What about at least a combination of 'visible' and 'hex'?
And I wouldn't mind a third and/or fourth obfuscation mode either ...


Before DokuWiki, I used a simple javascript to obscure against email collectors.

I can imagine a fairly simple scheme (xor site title against email
address) that could be easily done and probably fairly improbable for
a spider to figure out.

Essentially in php, xor name against title, output hex with function
call, and for javascript, do some kind of onclick or whatnot and
re-xor against the title(which would be hard coded in a javascript
var.)

I've not done a syntax plugin yet though; is it easy enough to
"overload" the email parser portion or would this have to be done in
the code itself? Or is this enough (Andi) for you to do yourself? If
not I could write up some concept code.


I think, Andi would not mind adding another obfuscation method into the core code. But that furher method should be usable *without* JavaScript!

As Andi has told me, another thing has to be considered when thinking
about new email obfuscation methods: The current two methods use the
generated obfuscated email address for displaying it as well as for the mailto link! That means, unless the original code is changed heavily, it is only possible to add new methods that can have the same string for both. So, any methods including e.g. images, are not appropriate. :-/


But implementing something more complicated or using JavaScript for it could make sense with a plugin ...
