Audio::M4P::Decrypt(3)User Contributed Perl DocumentatioAudio::M4P::Decrypt(3)

NAME
       Audio::M4P::Decrypt -- DRMS decryption of Apple iTunes style MP4	player
       files

DESCRIPTION
       Originally derived from the DeDRMS.cs program by	Jon Lech Johansen

SYNOPSIS
	use Audio::M4P::Decrypt;

	my $outfile = 'mydecodedfile';
	my $deDRMS = new Audio::M4P::Decrypt;
	$deDRMS->DeDRMS($mp4file, $outfile);

METHODS
       new
	    my $cs = new Audio::M4P::Decrypt;

	    my $cs_conparam = Audio::M4P::Decrypt->new(
	      strHome => '~', sPfix => '.', dirSep => '/' );

	   Optional arguments: strHome is the directory	containing the keyfile
	   directory.  After running VLC on a .m4p file	under Windows, MacOS
	   X, and Linux, this should be	found by the module automatically
	   (APPDATA dir	under Win32, ~/	under OS X and Linux). sPfix is	'.'
	   for MacOS/*nix, nil with Windows. dirSep is the char	that separates
	   directories,	often /.

	   For debugging purposes, use eg:
	    my $cs_conparam = Audio::M4P::Decrypt->new(
		DEBUG => 1, DEBUGDUMPFILE => 'm4ptree.html'
	    );

	   DEBUG turns on debugging output. DEBUGDUMPFILE is an	output file
	   name	to dump	an html	picture	of the m4p data	structure.

       DeDRMS
	    my $cs = new Audio::M4P::Decrypt( forceclean => 1 );
	    $cs->DeDRMS('infilename', 'outfilename');

	   Decode infilename, write to outfilename. Reading slurps up an
	   entire file,	so output can overwrite	the same file without a
	   problem, we hope. Backup first.  'forceclean	=> 1' will also
	   attempt to remove residual personal data from the file.

       DecryptFile
	   $cs->DecryptFile('infilename', 'outfilename');

	   More	descriptive alias for the DeDRMS method.

NOTES
	   This	software is designed to	allow different	but fair use of	music by the
	   purchaser of	the music. In no way is	this software intended to facilitate
	   use of digital music	files by parties other than the	purchaser of the
	   originally DRM-protected material. That is Fair Use,	corporate entities.

	   If you need to locate your iTMS keys, look for compatible versions of
	   JHymn or FairKeys, or use the LWP::UserAgent::iTMS_Client Perl module.
