Sometime ago it occured to me that the CoreModule Digest::SHA could be used to en/decrypt data.

What? No. And don't invent your own encryption.

It takes two lines of code to encrypt and decrypt properly. 

use Crypt::CBC qw( );

my $cipher = Crypt::CBC->new(
   -cipher => 'Blowfish',
   -key    => 'my secret key',
);

my $ciphertext = $cipher->encrypt("This data is hush hush");
my $plaintext  = $cipher->decrypt($ciphertext);
