Password Protect >>>
Encrypts a string by converting each character to it's ASCII key code. Supports two-way encryption - from a string to the numeric code, or from the numeric code back to the string. You can, for example, send the encrypted code to a friend and have them decode it with this script.
Add the below code to the <body> section of your page:
<script
language="javascript"
type="text/javascript">
var
str_in;
var
str_out =
"";
var
num_in;
var
num_out =
"";
var
e =
"Enter Text!";
function
str_to_num(form)
{
num_out
=
"";
if(form.input.value
==
"")
alert(e);
else
{
str_in
=
escape(form.input.value);
for(i
=
0;
i <
str_in.length;
i++)
{
num_out
+=
str_in.charCodeAt(i)
-
23;
}
form.output.value
=
num_out;
form.input.value
=
"";
}
}
function
num_to_str(form)
{
str_out
=
"";
if(form.output.value
==
"")
alert(e)
else
{
num_out
=
form.output.value;
for(i
=
0;
i <
num_out.length;
i +=
2)
{
num_in
=
parseInt(num_out.substr(i,[2]))
+
23;
num_in
=
unescape('%'
+
num_in.toString(16));
str_out
+=
num_in;
}
form.input.value
=
unescape(str_out);
form.output.value
=
"";
}
}
</script>
