The email encrypter on this page allows you to show your email to visitors of your site while hiding or obfuscating it from spammers, by scrambling or enciphering it. It transforms your email in a code you can put on your site. Visitors of your site, with Java activated, can read the email they can click on it to send you an email but it will be protected from spambots or email harvesters.
For most site owners, placing an email on the site so visitors can get in contact, is very important. Preferably visitors only need to click on the email address, write a message and sent it.
Unfortunately, putting your email on your site or any other place on the Internet, has become a problem. With the growing use of the Internet and emails, the problem of spam is also getting bigger and bigger. One of the things spammers do is email harvesting. That is, scanning the Internet to find emails to which they can send their spam. For this reason, it is not a good idea to put an email on you site just like that, without encrypting it. If you do, it won't take long before you start receiving spam, and it won't take long before you receive so many spam mails, it becomes difficult to find emails that interest you between them. That is why you need to protect emails on your site by hiding them from spammers.
Basically there are four ways to hide emails from harvesting bots.
The email encrypter on this page should provide better protection because it uses different keys for standard elements and non-standard elements of the email address. Moreover, it produces a Java script which needs to be run in the visitors browser to decode the email. It seems that, at least for the moment, spambots can not run Java scripts.
Using the same key for everything makes it too easy to find the email address. As said above, it is not very difficult to discover a key based on a standard. Standard elements like [mailto:] or the domain name can give away the key. Comparing the encoded email address with standard elements like this, makes it possible to derive the key and discover the enciphered email. Using a separate key for different parts of the email address makes it much more difficult to find the hidden email address. That is the principle behind the email encrypter on this page. Care was also taken that no part of the encoded email is recognisable anywhere in the produced Java script.
As can be expected from this page, I don't like spamming nor other invasion of privacy. Therefore I will not collect, much less pass to others or sell the email, entered in the fields, to be encoded. The code is generated automatically and, as far as I can control it, non of the entered or generated information will be stored or provided to others.
Some things still are for free. I use much of the free stuff available on the Internet, some of it is really good. That is one of the reasons I chose to place this email address encrypter on my site and allow visitors to use it for free, to contribute, to give something back.
To have your email enciphered or encrypted, type it in the given spaces, click [Generate] and the Java code will generated. Select all the Java code from the box. Copy and past it to the page where you want the email to appear, at the place where you want it to appear. For your visitors it will work as a normal [mailto] link. They can read it, click on it so their email program opens with the address in the right place, they can copy and past the email address. Email harvest bots will neither recognise it nor will they be able to decipher it.
This email encrypter will not be bot-proof forever but it is better than what I have seen. Until now (last update) it seems to work fine enough. Emails on this site don't seem to be harvested by spambots, only by human email harvesters. Automatic harvesting and spamming typically shows an exponential increase of spam which hasn't occurred and content of received spam is linked to the content of the site. Hopefully this email encrypter is going to work fine enough for quite a while longer.
Try it and if you like it, I would appreciate some feedback like a message on my message board, informing how well it worked. If you don't like it or found a problem, feedback will be greatly appreciated as well.
Please, leave intact, in the Java code, the note with author, link and copyright.
