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.
Invisible CHAOS Stego product for Windows with a CHAOS interface and a very large hiding capacity (~100% of carrier file).
BitCrypt 4.1 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.
Hermetic File Search - Index Module The index module of Hermetic File Search is for indexing HTML or text files in a hierarchy of files on CD, hard disk, etc. (not a website), so as to provide the data needed by the search module.
Hermetic File Search - Search Module The search module of Hermetic File Search is for searching HTML or text files (or similar) on CD or hard disk by keywords (searches can be on any word, all words or exact phrase). It uses data files produced by a previously-created index module.
Hermetic Word Frequency Counter This software scans a file, or text on the clipboard, and counts the number of occurrences of different words. The text can be in a language other than English. The words which are found and displayed can be ordered alphabetically or by frequency.
Hermetic Word Frequency Counter Advanced This software scans a text file, multiple files or text on the clipboard, and counts the number of occurrences of different words. The text can be non-English. The words which are found and displayed can be ordered alphabetically or by frequency.
Puffer Data file and e-mail encryption utility for Win 95 to XP. Uses 2048-bit Diffie-Hellman public key encryption with 256-bit AES algorithm for symmetric encryption.
Hiding CHAOS Stego product for Windows with a CHAOS interface and a very large hiding capacity (~100% of carrier file).
Tychicus Tychicus allows you to hide secret messages inside image files without visibly changing the image.
Lunar Calendars and Eclipse Finder A program to search for eclipses (lunar, solar, total, annular and umbral), to calculate the phase of the Moon at any given date and time and to convert between dates in the Gregorian and Julian calendars and dates in four lunar calendars.
Easy Date Converter Adds a number of days to a date, calculates the number of days between two dates, and converts among dates in various solar calendars: Gregorian, Julian, ISO 8601 Week, Hermetic Leap Weak and day-in-year (yyyy-ddd).
