Hermetic Stego 7.73 Description

"A steganography program to hide a data file within multiple BMP image files."

Editor: The art or science of hiding information is named Steganography. In one form or another it has been practiced since ancient times. With the development of computers it has become possible to hide the contents of a computer file (the data) in Another File (the container file) so that the insertion of the data file into the container file will not noticeably change the properties of that file. If the file which has been hidden is deleted (preferably using a secure deletion program such as Data Destroyer) then there is no indication that it even exists, but it can still be recovered when you need to get at it.

Good candidates for container files are graphics images, since it is possible to make small changes to the bytes specifying pixel color values in such a way that the "stego" image (containing the hidden data) does not look any different from the original image (the one which does not contain the hidden data).

Hermetic Stego allows you to hide a file of any type and of any size in one or more BMP image files, with or without the use of a user-specified stego key (an encryption key), so that (i) the presence of the hidden file is undetectable (even by forensic software using statistical methods) and (ii) if a stego key has been used when hiding the data then that data can be extracted only by someone who knows that stego key.

BMP images containing hidden data can be archived as a ZIP file and sent to another person as an email attachment. If one simply wishes to hide sensitive data (such as a file containing passwords, bank account Details, etc.) on one's computer, there are normally plenty of BMP files to be found there.

Another use for Hermetic Stego is to transport sensitive data (e.g., within an Excel Spreadsheet) without detection. One can hide the data in a set of BMP images and put those images on a memory stick (a.k.a. thumb drive). After reaching one's destination the data can then be extracted from the images. you can free download Hermetic Stego 7.73 now.
