∟Installing Crypt::ECB 1.45 with ActivePerl

A tutorial is provided to show how to install Crypt-ECB 1.45 module, that can be used together with Crypt::Blowfish (installed previously) to encrypt plaintext of any size.

Once we know what is Crypt::ECB, 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-ECB - 1.45", right-mouse click on it and select "Install..." command to mark it for installation.

4. Press "Ctrl-Enter" to run installation. Crypt-ECB - 1.45 will be downloaded and installed automatically.

5. Exit "ppm".

6. Enter a simple test script, Crypt-ECB-Blowfish-Hello.pl, with a text editor:

#- Crypt-ECB-Blowfish-Hello.pl
   use Crypt::ECB;
   $cipher = Crypt::ECB->new('my secret key', 'Blowfish');
   $ciphertext = $cipher->encrypt("The data is hush");
   print unpack("H*", $ciphertext), "\n";

7. Run the test script in a command window:

C:\Herong>perl Crypt-ECB-Blowfish-Hello.pl

Cool! I have correctly installed "Crypt-ECB 1.45", which is a Perl implementation of the ECB (Electronic CodeBook) block cipher operation mode. It can be used together with Crypt::Blowfish (installed previously) to encrypt plaintext of any size. I can write more Perl scripts to play with Blowfish cipher in ECB mode now. See next tutorials.
