4t HIT Mail Privacy Lite
4t HIT Mail Privacy Lite by 4t Niagara Software is a Win32 steganography program that hides up to 256 characters in a BMP and encrypts it with a password.
It reads a large variety of formats (jpg, gif, tga, eps, png, tif, wmf), but converts them all to one of three variants of bmp:
- straight bmp
- bmp in a zip file
- bmp in a zip file with the extension .hit
The .hit extension is associated with the program so you can open the files and be prompted for a password by double-clicking them (defeating the point of steganography, which is that no one realizes there is secret data in the first place).
