This is perl code. What you need is javascript code. I cannot remember
javascript functions of the top of my head so I think the best thing would
be to implement the algo at satya's page (the url is at the footer of his
mails).

This is also wrong and will not work. You will need this:
<script ...>
...
function validate() {
var toEncrypt=document.formname.fieldname.value;
var encrypted=encrypt(toEncrypt);
document.formname.hiddenfieldname.value=encrypted;
document.formname.fieldname.value="";
return true;
}
...
</script>
...
<form ... onSubmit="return validate();">
...
</form>
Of course, this will not work if the browser does not support javascript
or if javascript is disabled.

This is weird. See if you can decode the string, then anyone who has
access to your page can decode the string, so it makes no sense encoding
it in the first place.
If you still want to, then you will need to use an invertible funtion to
encrypt the data. I cannot give you a specific example, but constant XOR
is good.

Check satya's page for his XOR algo. I don't do encryption so I can't
help there.
