Security Considerations

It is a good idea not to always use the same PassPhrase for an extended period of time.  Changing and using different PassPhrases are the best way to secure your data.  Granted this is a hassle when sharing files with other people, but it is simply a fact of life in the encryption world.  Once someone has gotten your key and you continue to use it, the attackers will have access to your data.

The next two paragraphs are in regarding using the Key Management portion of the application.  Leaving your key file on your computer when you are not using it can be a bad idea as they could be copied or destroyed.  It is always a good idea to have your PassPhrases backed up to another media device and secured. In the Key Management window you can transfer (copy) the keys to another device, restore from that device and delete the keys from your system when you are not running Eureka.

Your key file (key.dat) is located in the folder where you are running Eureka.  You can easily give this file to someone else simply by encrypting it with a known PassPhrase and sending via email, etc.  Then when they decrypt it they need only set the decrypted filename to key.dat and place it in the folder where Eureka is run.  Care should be taken not to overwrite other keys in this way by first transferring your key file, loading up the new one and then using one of the cryptive areas to get the names and keys and then restore yours and then manually add the new ones.  It is highly recommended that you store your key data on external media especially USB drives.  That way they never reside on your hard drive.

In addition, at any time you can click on the keyboard button and get a graphical keyboard (english only) that can be used to defeat key loggers.  It is highly recommended that you use this unless you know for sure that a keystroke logging application is not running on your machine.
