What's New in Version 2.8 for the Macintosh?Much of the following material was developed by a team of graduate students at George Mason University. My thanks to them for putting these pages together and allowing their use.
Enigma is a low cost, easy to use application designed to completely protect your privacy. If you would prefer your neighbors not see your personal financial data, your coworkers not see your performance appraisal, or your competitors see your trade secrets then Enigma is an application you will find valuable.
Enigma supports both the Macintosh and Window's platforms. Encrypted documents can be exchanged between the two operating systems. (Note that at this time, vaults can not be used with the Window's version).
Enigma for Macintosh is distributed as demoware. You may freely download Enigma from this site and use it as much as you like, as long as you like without paying anything. The only things you can't do are sell it for a profit, or redistribute it represented as the work of anyone but Next Wave Software.
The demo version of Enigma uses a very weak (32 bit) encryption key and limits vaults to only 5 files. A 32 bit key is sufficent to keep casual snoopers and unsophisticated thieves from your data, it also happens to be legal to export. It is not, by any stretch of the imagination, strong encryption.
