in reply to Simple Crypt::CBC Sample?

I was unable to install Crypt::Random, so I can't even attempt to replicate your error.

However, if I run a modified version of your code with only Crypt::CBC, it runs for me without errors:

use warnings; use strict; use Crypt::CBC; my $key = 1; my $cipher = Crypt::CBC->new( -key => $key ); my $ciphertext = $cipher->encrypt_hex('test'); print "$ciphertext \n"; __END__ 53616c7465645f5f5847db7edbe4cfb66a7ce84481016e42

Perhaps there is a strange interaction between the 2 modules. Can you use something else to generate the key?
