This chapter explains how LexiGuard helps meet the need for
security of information.
LexiGuard™ secures
your files to minimize the exposure of your sensitive information without
compromising your access and use of that information. It offers:
-
Encryption/decryption of files or directories of your choice
-
Scalable levels of security with choice of algorithms
-
Password choices including mixed-case and mixed alphanumeric
passwords
-
Ease of use through an intuitive, user-friendly GUI
-
Two types of encryption offered, public key or password based
encryption
-
Multiple files can be encrypted in LexiGuard™ in a single
encryption operation. If all the files within a single directory have the
same list of recipients, you can recursively encrypt multiple files or
a sub-directory and all of its contents. The encrypted files reside in
the same directory as the originals.
-
The LexiGuard™ window offers two ways to do public key encryption:
-
Encrypt files to oneself—select the files or directories
in the file table and encrypt with a single click.
-
Encrypt files to other users—select the files or directories
and then specify the recipients of the encryption on a pop-up panel.
Only the proper recipient holding the corresponding private key can decrypt
the file.
New Features in LexiGuard Version 1.1
1. Password-based encryption and decryption of files.
Password-based encryption can be used to encrypt information
without using a public key or to send information securely to someone who
does not have LexiGuard in the form of a self-extracting file.
2. Sending a file by email from within LexiGuard with
a single click on the file. It's easy to send a key-encrypted file
to some or all of the people whom it was encrypted to. The email
address from their certificate tells LexiGuard where to send the file.
Or send an unencrypted file and specify the email recipients.
