Expanding Software on Linux
Password Protection and Compression Utilities

To speed-up and secure the electronic transfer of software for Linux, the software has been compressed using Info-ZIP Zip and encrypted using Info-ZIP Zipcloak.

To expand  and decrypt the software you will need Info-ZIP UnZip and Info-ZIP Zipcloak. Info-ZIP UnZip  ships with RedHat and other versions of Linux. Due to US export regulations, Info-ZIP  Zipcloak is not typically packaged with Linux bundles. Both utilities are available for free via electronic download from the following URLs:

Info-ZIP UnZip version 5.41 for Linux
ftp://ftp.freesoftware.com/.0/infozip/UNIX/LINUX/unz541x-libc5.zip

Info-ZIP Zipcloak for Linux
ftp://ftp.icce.rug.nl/infozip/UNIX/LINUX/zcr22x.zip

Once you have downloaded and installed the above utilities and modified your environment to  include them in your "path" statement, create the directory where you wish the software to exist and move the compressed, encrypted file to that directory. Before you can use  the software you must perform two tasks: First you must decrpypt it by switching to the  directory where the file is stored and typing the following:

zipcloak -d <filename>

When prompted, provide the password that was provided to you by support and the file will be decrypted. Now will perform the second task. From the same directory, type the following command to decompress the file:

unzip <filename>

The contents of compressed, encrypted file will now appear in the working directory. One of the files will be named "README". Open the readme file and following the instructions to install the software.
