The above figure lists the options available to the user.
The options menu of Enigma contains two selections: "General Options...", and "Clear Key". General options are those options which apply to all parts of Enigma. The Clear Key option provides a way to conveniently forget a key if you normally operate with Remember Key on. This will only be important if you regularly use more than one key to protect your files.
The above figure lists the options available to the user.
The first two options: Remember key during session, and Use default names for output will make it much easier to process large numbers of files at once. With both these options selected Enigma can operate unattended after a key is entered for the first file.
Selecting the Remember Key option will use the first key entered by the user for the entire session. The key will be erased from memory just before the application exits. If you wish to enter a new key during a session select "Clear Key" from the Options menu. If you accidently open a file with a different key from the "remembered" one, you will get an error message saying the key entered was invalid. If this happens the key is automatically cleared so you will be asked for a key again the next time you try to open a file or vault, even if the Remember Key option is on.
Selecting the Use Default Names option keeps Enigma from prompting you for an output name. If a file is being encrypted the output name will be the original name with the extension changed to .DSL or .DES depending on what version of Enigma you have. If a decryption is being done the output name will be the name of the document or application when it was being encrypted. (Enigma stores this information when the file is encrypted. The name is encrypted as well so it is as secure as the rest of the file.) Note: During decryption: if Use Default Names is selected you will be asked to confirm the deletion of any other file with the same name. If the file was originally encrypted on a Macintosh the file name might be truncated to fit into the limited filename space of DOS computers.
If this option is selected your key will be displayed with ?'s in place of the characters you type. You will be asked to confirm your key entry to be sure you didn't make a mistake. The confirmation process will assure that you don't enter an unintended key. Confirmation isn't done for decryption operations because the consequences of a mistyped key are much less drastic.
This option, if selected, will cause the computer to beep when encryption is complete.
If this option is selected you will be protected from accidently leaving Enigma running unattended, possibly allowing someone else access to your files. If Enigma detects no activity for the specified period of time it will clear the key from memory.
If you click on the "Save" button in the preferences dialog the options will be saved in a preferences file. You can also select the cancel button if you are not satisfied with your changes to the option selections.
