Steganos

Completely hide your data with Steganos

 A Windows 95 program

Are you afraid your data information is being looked at by eavesdroppers when you send it over the Internet. Steganos could be the program for you. It encrypts and hides sensitive data inside pictures, sounds etc. Picture files can still be viewed, sound files can be listen to, text files can be read, but nobody will know there is data hidden in them !

Steganos features include:

• 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", published by Wiley, ISBN 0-471-11709-9)
  
• Compresses files to hide 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
  
• 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 Windows 95 and Steganos Shredder are native 32-bit Windows 95 applications Hides all types of files
