Unlike cryptography, steganography makes an attempt to conceal the information in plain sight. Instead of creating an incredibly new and annoying encryption algorithm, steganographers will keep the original message intact, however, hidden from the unsuspecting eye. ByteShelter I Added 2004-10-13 This steganography tools lets you conceal data in Outlook e-mail messages and .doc files. Legion of the Bouncy Castle Java Cryptography API Added 2004-04-13 The Legion of the Bouncy Castle Java Cryptography API provides a lightweight cryptography API in Java, a provider for the JCE and JCA, a clean-room implementation of the JCE 1.2.1, generators for Version 1 and Version 3 X.509 certificates, PKCS12 support, and APIs for dealing with S/MIME, CMS, and OCSP. Versions are provided for the J2ME, and JDK 1.0-1.4. Steghide Added 2003-10-15 Steghide is steganography program which hides bits of a data file in some of the least significant bits of another file in such a way that the existence of the data file is not visible and cannot be proven. Steghide is designed to be portable and configurable and features hiding data in bmp, wav and au files, blowfish encryption, MD5 hashing of passphrases to blowfish keys, and pseudo-random distribution of hidden bits in the container data. Shadow-JPEG Added 2003-04-08 ShadowJPEG is a steganography example. It hides a file at the end of a JPEG image file. Cryptography is implemented using a simple private-key system which is used to encrypt the data before the injection. Stegdetect Added 2002-01-28 Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Currently, the detectable schemes are jsteg, jphide, and outguess 01.3b. appendX Added 2001-12-13 appendX is a steganography tool which simply appends data to other files (like JPEGs or PNGs) to hide it. It supports PGP header stripping. OutGuess Added 2001-10-22 OutGuess is a universal steganographic tool that allows the insertion of hidden information into the redundant bits of data sources. The nature of the data source is irrelevant to the core of OutGuess. The program relies on data specific handlers that will extract redundant bits and write them back after modification. In this version the PNM and JPEG image formats are supported. In the next paragraphs, images will be used asconcrete example of data objects, though OutGuess can use any kind ofdata, as long as a handler is provided. JPHS Added 2001-10-22 JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. EzStego Added 2001-10-22 This privacy utility demonstrates a new way of communicating securely. Want to communicate securely, but don't want to send large files of strange-looking numbers? Want to use strong crypto, but know that your email is not secure enough? Stego works like invisible ink for Internet communication. Stego can hide an encrypted text file in a GIF format image file - which is the most commonly used image format on the World Wide Web. The resulting GIF can be attached to an email message or posted on a web page. This source code is distributed copyleft. Browse by category |
