HTML Guardian FAQ - Technical issues
If I encrypt
HTML source, can it be edited with html editors?
No. It is not possible to edit the
encrypted HTML source in such programs and environments. Of course
you can modify it in text editors, but changing even a single character
in the encrypted code will result in a non-working file. When you encrypt
HTML code, any WYSIWYG editors such as DreamWeaver or Expression Web will
not be able to see it - protection will hide HTML source of the original
file from all programs.

How to remove the
banner from encrypted HTML and script files?
If you purchase HTML Guardian Professional
or HTML Guardian Enterprise Edition, the banner will not be included
in the encrypted files. You can do this here.
A complete comparison between HTML Guardian Personal, Professional and
Enterprise editions you can see here.
But we suggest that you first try the free Personal edition which has
all the features of the Professional / Enterprise editions. You can
download Personal edition here and test it as long as you wish, it doesn't have any time or functional limitations.

Will encrypted files be displayed
correctly in all browsers?
The current version of HTML Guardian has been tested
with versions 4.0 and higher of Internet Explorer, Netscape, Mozilla (and its various clones), Firefox, Opera,
Chrome, Safari browsers. However, encrypted files should work fine in any javascript
enabled browser on any platform / operating system. There is no requirement for a specific
version of javascript, the very first one is enough. HTML Guardian automatically
adds <noscript> tag to all encrypted html files, which will be
displayed if the browser is not javascript enabled(but such browsers
are something really exotic and hard to find these days).
Of course, files encrypted with the alternative encryption method(for
Internet Explorer 5+ only) will not work in other browsers.
Also, encrypted files will work in all browsers built on Internet Explorer(no
matter what encryption method was used), like NetCaptor, FastBrowser,
ClickGarden, etc.

Can I encrypt files created on Macintosh
computers?
Yes, you can. Note that Ascii files created on MAC/UNIX(like)
systems are different from ones created on Windows, although the differences
are not visible - Mac/UNIX use different characters to mark a new line.
That's why the files should be converted to Windows format before encryption.
HTML Guardian will detect and convert such files automatically in almost
all the cases, but if you have problems with files created on non-Windows machines,
you should convert them to Windows format before encryption.
There are several programs that can convert files from any format to
Windows format, like for example UltraEdit
(click File --> Conversions --> UNIX/MAC to DOS)

Will encryption increase the size
of the protected file?
Not really. Typically HTML Guardian will add less
than 1K to the encrypted files, if no additional options are used. If
you select all additional options, this will additionally increase the
size with about 1K. (For personal edition, additional 1K will be added
because of the HTML Guardian banner). This is practically nothing, it
will increase the download time with less than a second if your visitors
use 28.8 modem, which is something really rare these days.
The above applies only to small files, like 10K or smaller. If the file
to be encrypted is bigger, the encrypted file could be even smaller
than the original. That's because HTML Guardian compresses the code
before the encryption, i.e. it entirely removes the html formatting. All
unnecessary blank lines, new lines, tabs, spaces and so on(which otherwise
make your code look steady and easily readable) are removed, html and script comments are removed too.

How to encrypt multiple files at
once?
There are several ways to do that, choose the one that best fits your needs.
- To encrypt quickly all the files in a folder, click the 'Select folder' button, then
set the desired protection options and click 'Encrypt'. All appropriate
files in that folder will be encrypted(HTML, Javascript / VBScript,
ASP). Encrypted files will be saved in a Folder_name_E
folder under the same names. This method has some limitations - all
files will be encrypted with the same set of protection options.
- For maximum flexibility, use HTML Guardian's File List Manager. This
way you can encrypt at once sets of files which reside in different
directories, and you can use different protection options for each file.
- HTML Guardian also offers a full command line support. You can use
this feature to control HTML Guardian from another applications like
your own VisualBasic, C etc. programs.
File List Manager and Command line reference and some examples you can
see here.
- To encrypt an entire website (or any set of files that reside in one
folder) both for 'All' and 'IE5+' browsers with different protection
options for each file, use HTML Guardian's
Site Manager. It will make two separate encrypted copies
of your site and will generate a file which will redirect the visitors
to the appropriate encrypted version of your files depending on the
browser used. This way people that use IE 5 or higher(now about 90 %
of all web users) will see the files encrypted for IE 5+ browsers, and
the rest will see the files encrypted with the default method (for 'All'
browsers).
- You can perform most of the encryption tasks also in command line mode.

The encrypted file loads slow!
This could happen for big html or script files encrypted
for All browsers. If it takes too much time for the browser to process
the encrypted file, change the All browsers encryption method to Type
II or Type III - they are optimized for bigger files. You can do this
from the General Settings configuration
window.
In case enhanced website image protection is enabled, check the Image Guardian tab of the Settings window and ensure the program is not set to split images into too many pieces.

The encrypted file doesn't work!
There could be several reasons for that, but you can
be sure HTML Guardian is not one of them :)
Of course, first ensure that the original file works as expected. Make
sure you have the latest version of HTML Guardian - the latest version
available and the current built numbers of the Encryption engine and
CodeAnalyzer engine are always listed on our support
page. There you can also read about syntax requirements your
files should comply with, although they are very basic and simple.
Read the "Known Issues"
section of the Help.
To avoid errors, save encrypted file in the same folder as the original
under a different name - this will ensure that all relative paths are
correct.
Please carefully read HTML Guardian's Help file, "Known issues",
"FAQ" and other sections. Most of the problems you may have
when you encrypt html, script, asp, css files are explained there and
a solution how to fix them is suggested. For image protection issues,
read the "Image Guardian" section of the Help file.
Of course, you're are always welcome to contact our support
team in case of any problems.

Password protected file is displayed
even if I enter a wrong password.
This only looks like a bug. If you choose 'Display
blank page' in case of incorrect password, this could never happen.
If you choose 'Go back', but then you directly open the file(not by
clicking a link to it in another file) it could happen, if you're testing
the file offline. It could also happen if you choose to redirect the
visitor to another url and you're testing the file offline.
These problems will not appear when your protected page is requested
from web server.

Referrer check doesn't work.
This option will not work if you test the protected
page offline, you have to put it online. Always check pages protected
this way online! Note that some web servers does not support this option.
If the online test fails, you host your site on such sever - in this
case, don't use it.

You said HTML Guardian will dramatically
increase visits to my site, but there is no difference at all.
We said that it could do so, not that it will !
By encrypting your site, HTML Guardian will protect it from being blocked
by web content filters. Read more information here.
Many of our customers reported a noticeable increase in visits to their
sites immediately after they started to use HTML Guardian. Some of them
reported 2,3 or even 5 times more visits per day!
However, this depends on the nature of your site. If it is not likely
to be blocked by web content filters, you don't have to expect more
visits as a result of encryption. Also, HTML Guardian can't help if
the filters block your site by its URL.
There are two ways web content filters block sites - by URL and by scanning
the html code for certain keywords. Using the first method only is now
considered unreliable because it requires maintaining huge databases
with millions of URL's which has to be updated daily. Good content filters
use both methods together. You can be sure that eBay.com, Amazon.com,
Formula1.com, Travel.com, Download.com or mp3.com are blocked by their
URL's. But sites which are not so popular and are not in the URL blacklist,
are blocked after scanning their code for 'bad' words. If this is the
case for your site, HTML Guardian can surely help.

I lost my original files! Can you
help me recover them?
Sorry, we can't do this. Please don't ask us. We regularly
receive emails like "I replaced my original files with encrypted
ones by mistake, can you help me recover them?". We did our best
to help users of HTML Guardian avoid such problems. HTML Guardian will
never overwrite the original file with the encrypted one by default.
The only exception is if you use batch file to encrypt multiple files
at once, and you specify the same filename for the input and the output
file.
So be careful when creating batch files, and please always backup your work.

Where is CodeAnalyzer? How to access
it?
CodeAnalyzer is still here. However, since version
5.0 all the Code Analyzer engine settings can no longer be accessed from
the user interface. During the beta test period we found that the too
many options it has tend to confuse the users. That's way the CodeAnalyzer
engine was almost completely rewritten. Now it runs in the background
and sends feedback commands to the Encryption engine without the need
of user intervention - the program automatically decides which values ensure best security and performance.
However you can still configure the most important Code Analyzer engine
settings from the Profiles and Advanced Settings
window (read more in HTML Guardian's Help file)

I can't install HTML Guardian Personal
edition!
In some rare cases you may have problems installing
HTML Guardian, like error messages during install process, or continuous
prompts to reboot your system in order to update system files (Note:
On some systems you may be prompted to reboot once so
that the installer can update system files that are in use - this is
normal, please follow the instructions).
These problems are due to some bugs certain versions of Windows system
files have.
If you encounter installation problems, click here
to download HTML Guardian Mini Setup.
Mini Setup only contains HTML Guardian core files and does not include
any Windows system files, but they are already available on most Windows
PC's because almost all programs install and update them.

I see an error message when I try
to start the Auto Update Utility.
This is because some standard Microsoft controls are
missing on your system.
Please download this
file and follow the instructions in Readme.txt to solve
the problem.

I see an error message "Component
'xxxxx.yyy' or one of its dependencies not correctly registered: a file
is missing or invalid " when I start HTML Guardian or when I
try to use some feature. What to do?
This means some .ocx or .dll file is either missing,
corrupted or improperly registered on your system. HTML Guardian setup
package includes all such files which the program needs to run, but
you can still see this error message in some cases ( for example if
you uninstall some other program, the uninstaller may remove some file
which HTML Guardian needs ).
If you see this message, please download this
file and follow the instructions in Readme.txt to solve
the problem - this file contains most of the system files you may need.
If the file needed is not included, you can mail our support team for
it, but you can also find it yourself - just go to Google
or some other search engine and enter 'xxxxx.yyy' or 'download xxxxx.yyy'
as a search phrase - there are a lot of sites from where you can download
.ocx or .dll files.
After you download the missing file, copy it to your \System32 folder.
Then click Windows 'Start' button, click 'Run', in the box type
regsvr32 xxxxx.yyy
and click OK. You will see a message that the operation succeeded - something like 'DllRegisterServer in xxxxx.yyy succeeded'. That's
all, the problem should be fixed.

HTML Guardian crashes when started
on WindowsXP
In some very rare cases, when you start HTML Guardian
on a WindowsXP system, you may see an error message like:
"HTML Guardian has encountered an error and needs to close"
or similar (or the program may just quit without any error message).
This can be caused by some "tweaking" programs, for example
WindowsBlinds and similar ones that carelessly modify the registry.
If you experience such problem, go to HTML Guardian's installation folder
(most likely C:\Program Files\HTML Guardian ). Right click on the htmlg.exe
file and select 'Properties' from the context
menu. Click the 'Compatibility' tab. Check the
'Disable visual themes' box. If available, check
also the 'Turn off advanced text services' box.
This settings changes will be applied only to HTML Guardian and will
not affect other programs.
If the above doesn't seem to help, please check the related
information in the program's help file.

HTML Guardian works slow
Could be, on relatively slow machines. HTML Guardian
is very different
from all other HTML Guardian - like programs. It performs a deep analysis
of your source code first, in order to predict and avoid possible problems
and to select the best possible protection for each file. It also tests
and debugs the encrypted output and in case of failure, or in case the
encrypted file security is unsatisfactory, it may restart the encryption
process. All this takes time, but ensures maximum security and performance
for the encrypted files.
There are however ways to improve the encryption speed:
- if you do not intend to use Image Guardian, disable it. If it is enabled,
the CodeAnalyzer™ engine and the debugging engines perform a lot
of additional tasks.
- disable Multi-language support if it is not actually needed. Multi-language
support is not needed for pages that are in English and in most of the
West European languages like Spanish, Portugese, French, German, Italian,
Dutch etc.
Of course, if you experience problems when you encrypt html files
that use West European languages, you should enable Multi-language support.
