bmpPacker is a portable encryption tool that camouflages the encrypted file inside a Windows Bitmap (.bmp). You can select any file (documents, image etc.) and the program will generate a fully compatible BMP container file that contains the encrypted file. The carrier image is fully windows compatible but only displays a bunch of noise when opened - to decrypt and extract the contained file, you'll need to open the BMP file with bmpPacker and supply the proper password, which will then decrypt/extract the contained file. bmpPacker supports Blowfish, Twofish and Rijndael (AES) algorithms for secure encryption.
