Installing Crypt::Blowfish 2.14 with ActivePerl

A tutorial is provided to show how to install Crypt-Blowfish 2.14 module originally developed by A.M. Kuchling with ActivePerl 5.18 on Windows.

Once we know what is Crypt::Blowfish, we may want to get it installed and try it. Here what I did to install it with ActivePerl 5.18 on my Windows system:

1. Run "ppm", the Perl Package Manager.

2. Click menu View > All Packages, to see all packages.

3. Find "Crypt-Blowfish - 2.14", right-mouse click on it and select "Install..." command to mark it for installation.

4. Press "Ctrl-Enter" to run installation. Crypt-Blowfish - 2.14 will be downloaded and installed automatically.

5. Exit "ppm".

6. Enter a simple test script,, with a text editor:

   use Crypt::Blowfish;
   my $key = pack("H16", "0123456789ABCDEF");
   my $cipher = new Crypt::Blowfish $key;
   my $ciphertext = $cipher->encrypt("plaintex");
   print unpack("H16", $ciphertext), "\n";

7. Run the test script in a command window:



Cool! I have correctly installed "Crypt-Blowfish 2.14", which is a Perl implementation of Blowfish originally done by A.M. Kuchling. I can write more Perl scripts to play with Blowfish now. See next tutorials.
