PassPhrase Management allows you to store PassPhrases in a file so you won't have to key them in manually each time. Each PassPhrase is assigned a name for easy retrieval. These names are populated in the combo box either to the side or underneath the PassPhrase box throughout the program, and the PassPhrase for that corresponding name is populated in the PassPhrase field.
The Key Update section is where you either add or update a PassPhrase. To add a new one, define the name to reference the PassPhrase and the PassPhrase itself and click on the Add/Update button. In order to defeat keystroke logging programs, you can click on the Keyboard button and enter in the PassPhrase virtually.
To Update a PassPhrase, click on the item in the Current Keys section. This will populate the name and PassPhrase fields. You can then alter the PassPhrase and click on the Add/Update button.
The Security section deals with transfering (copying), deleting and restoring the PassPhrase file. It is not a good idea to leave this file on your hard drive when it is not in use. This file should reside on multiple USB drives or some other dependable external storage device. They can be then restored as needed and then deleted to ensure security of your PassPhrases.
Transfer will copy the PassPhrase file to the device/folder you specify. Delete will remove the PassPhrase file from your hard drive. Restore will take the specified device/folder you specify and copy it to your hard drive.
The keyspace is a series of files that Eureka creates for each PassPhrase at process time. These files are used by Eureka to encrypt/decrypt the data. Depending on the Depth of the process (see PassPhrases and Depth) will determine how long it takes to create the keyspace. The greater the Depth, the longer yet more secure than smaller depths.
For this reason, you have the ability to create these larger keyspaces, so you won't have to wait a long time just to create it again when you use it. To create a keyspace from the main menu click Keys then Create Key Files, then define the folder where to put them, select a prefix for the files, determine the PassPhrase and Depth then click Create. The prefix is used so you can store multiple keyspaces in the same folder. Each file will be followed by the next number in sequence - for example if you specified a prefix of 'GA' you would create the files GA1.bin, GA2.bin, GA3.bin and so on.
To restore a created keyspace from the main menu, click on Keys then Restore Key Files, define the path to where they were saved, define the prefix used and click on Restore. The created keyspace is now in place.
When you go to any routine click on the check box for Use Existing Key to use the restored keyspace, otherwise the program will use the PassPhrase instead and create a new keyspace. In that event you will need to restore it again.
