The CMSB records for my client's web site contain an e-mail address field that gets inserted into a membership directory web page.

I’ve been trying to find a method to encrypt the e-mail addresses that appear in the source code of the membership directory web page so that they can’t easily be harvested by bots.

I’d still like to allow a user to click on the e-mail link to open their e-mail client.

So far I’ve only found very cumbersome single address only solutions.

Any ideas?

Thanks,

Hi Jerry,

I'm not sure about that one. It's tricky because in order for the user to be able to click on it and send an email the browser needs to be able to get the email address, and if the spam parsers implement a browser (and/or javascript engine) they can get the same thing.

There's this: http://mailhide.recaptcha.net/ but users need to enter some words to display the email.

I've thought about writing a PHP module that could be included on the top of any PHP page to automatically replace emails with images or some encoded version. Then than could be used on any PHP page at all. If there was interest in that as a script we could look at writing that.

Hope that helps!

I think that there's probably a great deal of interest but no one really knows where to start.

Security and privacy have become major issues of late.

I think it would be great if you got the ball rolling.

Could even be a mini product idea...

Dave,

I am interested. What do you think would be fair as far as price? I would probably pay up to $50 for something like that.

Anybody else?

Since you asked, and since your entire program sells for $139.95, I think somewhere in the range of $20-$25 would be OK. (kind of a thanks for putting this at the top of your list)

This probably wouldn't pay for a lot of development time, but it would certainly reinforce that idea that security is a major concern that's taken seriously at InteractiveTools.

If it were an unlimited use lifetime payment then I would suggest that $50 is a decent price but if requiring a lot of hours to develop then even $100 would be fair.
