Managing LexiGuard Users



LexiGuard maintains two types of users; internal users and external users. Internal users have two keypairs, one for encryption and one for signing. External users have a public key to permit them to be recipients of encryption.

Managing LexiGuard Internal Users

Below are procedures to manage LexiGuard internal users. The procedures are performed from the Internal Users pane of the Users Panel.

To access the Internal Users pane:

Adding New Internal Users

To create a new internal user:
1. Click the Add User... button.
    The Add User panel displays

2. Type the user's First Name, Last Name, Login Name, Password, and Email address.

Note: All fields must be completed.

Removing An Internal User

Select a user by login name from the scrolling list then click Remove User.

Exporting An Internal User to a File

1. Select a user by login name from the scrolling list.

2. Click Export User...
    A dialog box appears that prompts for the password for that user.
    Enter the password—a File Chooser window is displayed.

3. Browse to the desired target directory and specify a file name for the exported certificate file.  A file of extension .cer or .p12 can be generated.

Note that there is an enormous difference between these two types of files.
A .cer file contains only the public key certificate.  On the other hand, a .p12 file contains both the private key (protected by the password) and the public key certificate.

Viewing the Certificate of an Internal User

Select a user by login name from the scrolling list then click View Certificate.  A dialog box displays the contents of the encryption certificate for that user.

Managing External Users

Below are procedures to manage LexiGuard external users. The procedures are performed from the External Users pane of the Users Panel.

To access the External Users pane:

1. Click Users... on the Tools pulldown menu
2. Select the External Users tab

Importing a Certificate

To encrypt a file to another user, you must have the public key of that user.

Click the Import User... button on the External Users pane. A File Chooser panel appears.

Browse to the desired directory to select a file which contains the desired user certificate. Files of extension .cer or .p12 can be imported. The Certificate File filter can be selected to display only the files with those extensions.

When you  select a file and click Open, a popup dialog box prompts you for the password for this certificate file. Another popup dialog box prompts you for a user name for the new external user.

Removing an External User

Select a user by login name from the scrolling list then click Remove User.
You are prompted to confirm that you want to delete that user.
If you click Yes, the external user is removed.

Viewing the Certificate of an External User

Select a user by login name from the scrolling list then click View Certificate. A dialog box appears which displays the contents of the encryption certificate for that user.

Managing Keys and Certificates

The keystore files can be archived or backed-up. Since the keys are password-encrypted, the key data remains safe.
