Product Info


We have designed several systems for the various uses of Eureka, and we have the right version for your data security.  Compatible with Windows '95, '98, 2000, ME, XP and NT.


Macintosh versions are available for Public Key, Messenger and the v6 Global Edition.


Linux versions are also available for Public Key, Messenger and the v6 Global Edition.

Eureka products contain no backdoors and none of the data contained in the encrypted files serve as an aid to deciphering the original contents.   Not one of our clients over the past <%= yrstr %> years have ever reported the data secured by Eureka to have been compromised.  None of the software contains adware or spyware.

The Eureka 5.5.2 Enterprise version also contains Merge encryption, Multiple encryption, Scrambling, File Insertion - Extractions and more!

All Windows applications (except those with Linux and Macintosh counterparts) require the Visual Basic 6 runtime files.  If you require them (if you have an XP or Vista, you do not need them) in order to run the Eureka applications you can download them here.   If you still have problems (and you shouldn't), do a web search for 'vb runtime' and there are many other resources to help you.

A Mainframe version is now available.  See the description in the Commercial Products section.

About Eureka Encryption

Take a look at some of our program screens.Visit the Information and the Disclaimer areas.  See some actual examples of our encryption, or try one of your own. 

Eureka was developed with former military cryptographers who know the best encryption so you do not need to consider Eureka Snake Oil.

We have challenged the best to break our encrypted files.  No one (without exception!) has ever decrypted an Eureka encrypted file without using Eureka and the original encryption scheme settings for decryption - even when they know the contents of the original message Any persistent programmer can disassemble our object code - It does not matter!   Cryptanalysts around the world using the world's fastest and most sophisticated computers dedicated to resolving Eureka have been unsuccessful.  No one is able to decipher the encrypted files or messages produced by our software.

Your privacy is a very serious matter.  Eureka software products have been designed to be easy to configure for personal data security.  More complex configurations can be encoded to provide an even higher degree of security for corporate data - all types of data files can now be secure.  We can also provide special methods to corporate purchasers (whose encryption schemes may be compromised) that allow their security officers to quickly and effectively re-secure their data - whenever necessary or as a part of standard security procedures.

Eureka is fast, too.   Even better, it's all free!  Visit the Download section to start using it today.   For all of your data security needs, there is simply nothing better than Eureka Encryption Technology.
