Hermetic Stego
	Hermetic Stego is a steganography program which allows you to encrypt and hide the contents of any data file in another file so that the addition of the data to the container file will not noticeably change the appearance of that file. If the file which has been hidden is deleted then there is no indication that it even exists, but it can still be recovered when you need to get at it. This program allows hiding a file of any size in one or more BMP image files, with or without the use of a user-specified stego/encryption key, so that (i) the presence of the hidden file is undetectable (even by forensic software using statistical methods) and (ii) if a user-specified stego key is used then the hidden file can be extracted only by someone, using this software, who knows that stego key. Hermetic Stego allows two operations: (i) hiding a message file in single BMP image file or in a set of BMP images and (ii) extracting a message file from a single BMP image file or a set of them. This program differs from others of this sort in two respects: 1. There is no limit on the size of the data file to be hidden because Hermetic Stego can hide a data file, not just in a single BMP image file, but in a set of them -- as many images as needed to contain the data file. 2. The bits of the data are inserted into the bytes of the image files randomly and in such a way as to defeat the use of statistical tests to reveal the presence of a hidden message. 3. The program can be used with a user-specified stego key or with a default stego key; use of a default stego key allows sending hidden data to another person who does not know what that stego key is.

	BitCrypt
	BitCrypt is a sophisticated encryption application allowing for storage of text within an image. It is designed for persons who wish to store or communicate information in an invisible manner. The main strength of the program is the ability to hide the information from any unauthorized observer. The encryption is not visible, and the encoded text does not seem to be present in a seemingly unchanged image. While encrypting, BitCrypt modifies the individual pixel shadings of the image, and in this way incorporates the textual information. The modification of the image is so small that the effect is not perceptible to the human eye. The program uses stego technology to achieve this objective. BitCrypt has been originally designed with Intelligence community in mind. However, it became a favorite tool of anyone wishing to communicate in an invisible manner. The text is encrypted with one of the strongest encryption algorithms in order to strengthen the level of security. The program is distributed in completely functional form as freeware.

	MSU Stego Video VirtualDub Video plugin
	Free plugin for hiding information in video. Data that you hide can be recovered even from compressed video, or if the video was compressed again by another codec! We smartly change video with understanding how codecs works, introducing small amounts of noise. You can hide not so big files, but for cipher communication or video secret marking it's enouch! You can manage redudancy of information in film - if you want to compress video with low bitrate, you should increase redundancy, and vice versa.
