File Mask is a robust steganography application designed to encrypt and conceal your personal files. File Mask allows you to encrypt and hide your sensitive files within ordinary digital images using 256-Bit encryption and our TrueStego technology. Files hidden with File Mask are undetectable and cannot be recovered without the correct password. You can encrypt and hide any file type with File Mask including ZIP files. Images containing hidden files are fully functional and are identical to the original image. File Mask is an ideal application for persons who share very sensitive data with colleagues, family, or friends, and require that data to remain secure. File Mask is more than just an encryption application; it is also an electronic mask for your files, thus making your documents secure and invisible.
