NAME ^

Code::Crypt::Graveyard - Encrypt you code with multiple nested keys

VERSION ^

version 0.001000

SYNOPSIS ^

 use Code::Crypt;
 use Code::Crypt::Graveyard;

 print "#!/usr/bin/env perl\n\n" . Code::Crypt::Graveyard->new(
    code => 'print "hello world!\n";',
    builders => [
       Code::Crypt->new(
          get_key => q{ $] },
          key => $],
          cipher => 'Crypt::Rijndael',
       ),
       Code::Crypt->new(
          get_key => q{ $^O },
          key => $^O,
          cipher => 'Crypt::Rijndael',
       ),
       Code::Crypt->new(
          get_key => q{
             require Sys::Hostname;
             Sys::Hostname::hostname();
          },
          key => 'wanderlust',
          cipher => 'Crypt::Rijndael',
       ),
    ],
 )->final_code

DESCRIPTION ^

Code::Crypt::Graveyard leverages Code::Crypt to encrypt code in a nested fashion. This can help to keep what inner keys are a secret. In the example given in the "SYNOPSIS" the outermost key is the hostname. The inner keys are the operating system and the perl version. Of course, as with Code::Crypt, a technically proficient user that the code is targetted towards can likely remove all encryption entirely.

METHODS ^

final_code

 my $code = $cc->final_code;

This method takes no arguments. It returns the compiled code based on the "ATTRIBUTES".

ATTRIBUTES ^

code

required. The code that will be encrypted.

builders

required. An arrayref of Code::Crypt objects that will encrypt the "code" recursively. Innermost is first.

SEE ALSO ^
