OmniHide PRO
From Just Solve the File Format Problem
OmniHide PRO is a Win32 program that hides a file in another file.
It only supports hiding 1 file in another, there is an option for password protection, and there is a free OHP Extractor.
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.
In 'Secure Mode' a password is required to extract the file.
The trial has several restrictions:
- Carrier file must be an image between 300x300 and 1440x1440
- A watermark will be added to the image
- Can't password protect/encrypt files
Several weaknesses were identified:
- The filename of the hidden data is stored in plain-text
- The hidden data is not compressed, making it it easy to determine the size of the embedded data
- A large quantity of consecutive spaces makes it easy to identify carrier files
