WHAT IS STEGANOS FOR WINDOWS95/NT4.0? Steganos [Greek]: protected, protecting; covered, covering. Thank you for trying Steganos for Windows95/NT4.0. Steganos is an easy to use, yet powerful wizard style program to hide and/or encrypt files. Steganos encrypts files and hides them within BMP, DIB, VOC, WAV, ASCII, and HTML files. (For a complete listing of features see section 6.) When using only cryptographic methods, data may be unreadable but it is obvious that there is sensitive data - that there is a secret. If data is only hidden and not encrypted one could search all suspicious carrier files for hidden data and perhaps find sensitive information. Steganos combines two powerful methods: Cryptography - to make data unreadable to anyone who does not know the password - and steganography - to hide the existence of data. Files being hidden and encrypted by Steganos can be neither read nor detected easily. It could become necessary to hide the existence of information. The government could someday force you to give out your passwords or even forbid strong cryptography, so stand-alone cryptography wouldn't make sense any more. Be prepared - with Steganos for Windows95/NT4.0. 3. THE SHAREWARE IDEA If you see a shareware screen when starting Steganos you are using the shareware version. You may use it for 30 days. If you want to continue using Steganos after your 30 day evaluation period you must purchase the registered version. Otherwise, you must remove the shareware version from your system. Click the Order Steganos button on the Steganos start screen for further information. All shareware screens are left out in the registered version. You may - you even should - give the unregistered test version to your friends. The program itself, the documentation and all other files must be passed in their original, unchanged form. Use of this software is permitted only to the extent reasonably required to determine whether to purchase the software. After payment is made, use of this software is limited to use on only a single personal computer or workstation which is not used as a server. An additional payment is required for each use on another personal computer or workstation. Only a single copy may be made of this software solely for backup or archival purposes. The software may also be transferred to a single hard disk. Any use of this software in violation of the above is not licensed. 4.

ORDERING THE REGISTERED VERSION See order.txt for ordering details if you are inside the USA or Canada. See orderint.txt if you are in any other country. 6. FEATURES - Hides all types of files within image files (BMP, DIB), sound files (WAV, VOC), and all types of ASCII text files or HTML documents. - Easy to use Wizard style interface which will guide even absolute beginners through the program while allowing effective usage by advanced users - Allows encrypting files only (without hiding) as SEF files (Steganos Encrypted File); can be decrypted by simply double clicking on an SEF files' icon - Strong encryption: The used HWY1 encryption algorithm generates an output stream which is compatible to the "Alleged RC4" ("RC4" is a trademark of RSA Data Securities Inc.) output stream as posted by the Cypherpunks on the Usenet. Steganos for Windows 95's implementation of this algorithm was developed entirely from the description of Bruce Schneier (see "Applied Cryptography", Wiley, ISBN 0-471-11709-9). - Compresses files to hide using a to increase efficiency (using zlib by Jean-loup Gailly and Mark Adler. They are members of the Info-ZIP group and provided code for the popular WinZip program) - Converts pictures with few colors to 16.7M color images (24 bit format) - Features hiding files only (if data has already been encrypted) - Hides in carrier files of unsupported format after the user entered some information on the carrier file - Features backing up carrier file before hiding data inside - Optionally wipes file to hide after being hidden/encrypted - Encrypted files and files in which data has been hidden can be sent via e-mail by one mouse click - Does not change the carrier's file date and time to not cast suspicion on the file - The Steganos SDK (Software Development Kit) is offered to developer's for letting them advance their programs with the functionality of hiding/unhiding data (see STE_SDK.zip) - Contains Steganos Shredder, a program which wipes files from your hard disk irrevocably (the user simply right clicks on a file and chooses Send to... Shredder) - Contains UpdateNOW! technology that makes it easy to update Steganos using the Internet - Both Steganos for Windows95/NT4.0 and Steganos Shredder are native 32-bit Windows95/NT4.0 applications 7.
