NAME
    PerlIO::via::CBC - PerlIO layer for reading/writing CBC encrypted files

SYNOPSIS
      use PerlIO::via::CBC;

      PerlIO::via::CBC->config(
        'key'             => 'my secret key',
        'cipher'          => 'Blowfish',
        'iv'              => '$KJh#(}q',
        'regenerate_key'  => 0,   # default true
        'padding'         => 'space',
        'prepend_iv'      => 0,
        'pcbc'            => 1  #default 0
      );

      my $fh;
      open($fh, '>:via(PerlIO::via::CBC)', $file)
        or die "Can't open $file for encryption: $!\n";
      print $fh $lots_of_secret_data;
      close($fh)
        or die "Error closing file: $!\n";

      open($fh, '<:via(PerlIO::via::CBC)', $file)
        or die "Can't open $file for decryption: $!\n";
      print <$fh>;
      close($fh)
        or die "Error closing file: $!\n";

DESCRIPTION
    This module implements a PerlIO layer that can read and read CBC
    encrypted files. It uses Crypt::CBC to do the CBC. So check Crypt::CBC
    for more information.

  config(%args)
    Allows the configuration of the CBC. Check Crypt::CBC->new() for more
    information.
