Although not absolutely necessary, it is highly recommended that you
have all target browsers installed on your system. In the process of
debugging the encrypted page, the CodeAnalyzer™ engine and the debugging engines may need to interact
with them if a situation not found in their database occurs.
We are continuously updating and improving CodeAnalyzer's database,
so in 99% of all cases your files will be correctly encrypted even if
you don't have any browser installed. But if you do have the browsers
installed, this percentage will slightly increase (to 100% :)
Current version: HTML Guardian Personal/Professional/Enterprise
edition - 7.9.1
CodeAnalyzer™ engine: build 95
Encryption engine: build 59
Debugging engine: build 71
Security auditor: build 34
Supported browsers: please see our FAQ
Syntax requirements: to ensure proper encryption, your files
should comply with some very basic and simple syntax requirements. Html
files should always have opening and closing html, head and body tags.
Frameset files should always have opening and closing html and head
tags and should not have a body tag. There should be no code outside
the head or body tags.
In many cases files that don't comply with the above requirements will
be displayed in browsers without errors. However, HTML Guardian needs
these requirements to be fulfilled to ensure proper encryption for all files.
Before contacting our support team, please ensure
problematic files have proper code syntax. See also the Support section of the Help file, it contains more troubleshooting information.
Almost always, the reason for the non-working encrypted
files is the improper syntax of the original
file.
Example of a file with a valid syntax:
<html>
<head>
..head tag content comes here...
</head>
<body>
..body tag content comes here...
</body>
</html>
The most common cases of improper syntax are files in which one or more
of the
<html> , </html>
, <head> , </head>
, <body> , </body>
tags is missing or is not in the right place (for example <body>
is before </head>).
Another common source of problems is putting code outside the <head>...</head>
and <body>....</body> tags,
for example:
<html>
<!--There should be no code here, not even comments
-->
<head>
..head content comes here..
</head>
<!--There should be no code here, not even comments
-->
<body>
..body content comes here..
</body>
</html>
Incorrect html and script comments may also cause problems:
A correct html comment looks like this <!--some
comment -->
There should be no space after <!--,
and there should be one space before -->
There should be no html comments inside script tags (except the commonly
used <!-- at the beginning
of the script and //-->
at the end to hide the script from old browsers - but these tags are useless
if you intend to encrypt the file, and the browsers for which they are
needed practically do not exist anymore - so you better don't put <!--
...... //--> in scripts
at all).
Unclosed tags (for example an <Object ... > tag without a closing </Object>
tag) or invalidly nested tags may also cause encryption failure sometimes.
Contacting technical support:
To contact our technical support team, please email to support@protware.com.
You will receive a reply typically within one business day, often faster.
Please note that at this time we do not provide technical support for
encryption of php files. However, please inform us for any problems
you have when you encrypt php files.
Problems with encrypted files:
If you have problems with encrypted files, please before contacting
our support read our FAQ
and the 'Known Issues'
section of the Help file and ensure that you have the latest version
of HTML Guardian. The latest version available is always listed on this
page, and you can see your version by clicking 'About' in the Help menu.
To be able to help, we need to reproduce your problem first. So please
zip and send us the file that is causing
the problem (of course, unencrypted:) together with all the files referenced
in it (images, script files, applets, etc). Please also provide the
following information:
- a brief description of the problem
- protection options used
- your operating system
- in what browser the problem appears - if the problem only appears
when you open the file with a specific browser, please tell us the name,
version, build, etc. Also, let us know if this browser is installed on the same computer where you encrypted the file.
Plain text files (like html, scripts, css, asp etc.) are often altered
when sent as email attachments. That's why we kindly ask you always
to send us whatever attached files zipped
- we need to be sure we are testing exactly the same files as you.
We will use your files only for debugging and will delete them after
the problem has been identified.
Please direct your questions regarding beta versions of our products
to betatest@protware.com.
Please do not send encrypted files asking us to restore the originals
- we can't do that. Backup your files often to avoid accidental data
loss.
