&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{FormatInfo&lt;br /&gt;
|formattype=electronic&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
'''OmniHide PRO''' is a Win32 program that a file in another file.&lt;br /&gt;
&lt;br /&gt;
It only supports hiding 1 file in another, there is an option for password protection, and there is a free OHP Extractor.&lt;br /&gt;
&lt;br /&gt;
In 'Portable Mode' there is no password protection and if the file being hidden is a zip or rar, it can be recovered by a standard tool like WinZip or WinRar without using OHP.&lt;br /&gt;
&lt;br /&gt;
In 'Secure Mode' a password is required to extract the file.&lt;br /&gt;
&lt;br /&gt;
The trial has several restrictions:&lt;br /&gt;
* Carrier file must be an image between 300x300 and 1440x1440&lt;br /&gt;
* A watermark will be added to the image&lt;br /&gt;
* Can't password protect/encrypt files&lt;br /&gt;
&lt;br /&gt;
Several weaknesses were identified:&lt;br /&gt;
&lt;br /&gt;
* The filename of the hidden data is stored in plain-text&lt;br /&gt;
* The hidden data is not compressed, making it it easy to determine the size of the embedded data&lt;br /&gt;
* A large quantity of consecutive spaces makes it easy to identify carrier files&lt;br /&gt;
