OMA::Download::DRM - Perl extension for packing DRM objects according to the OMA DRM 1.0 specification
This module encodes data objects according to the Open Mobile Alliance Digital Rights Management 1.0 specification in order to control how the end user uses these objects.
use OMA::Download::DRM;
my $drm = OMA::Download::DRM->new(%args);
Returns download object uid
print $drm->uid;
Returns the MIME type
print $drm->mime;
Forward-lock delivery
my $drm = OMA::Download::DRM->new( 'content-type' => 'image/gif', # Content MIME type 'data' => \$data, # GIF image binary data reference ); print "Content-type: ".$drm->mime."\n\n"; # Appropriate MIME type print $drm->fw_lock(); # Forward lock
Combined delivery
my $drm = OMA::Download::DRM->new( 'content-type' => 'image/gif', # Content MIME type 'data' => \$data, # GIF image binary data reference 'domain' => 'example.com' ); print "Content-type: ".$drm->mime."\n\n"; # Appropriate MIME type print $drm->combined($permission, %constraint); # Combined delivery. See OMA::Download::DRM::REL.
Separate delivery. Content encryption and packing.
my $drm = OMA::Download::DRM->new( 'content-type' => 'image/gif', # Content MIME type 'data' => \$data, # GIF image binary data reference 'domain' => 'example.com', 'key' => '128bit ascii key' ); print "Content-type: ".$drm->mime."\n"; # Appropriate MIME type print "X-Oma-Drm-Separate-Delivery: 12\n"; # The terminal expects WAP push 12 seconds later print $drm->separate_content($rights_issuer, $content_name); # Encrypted content
You then need to send the rights object separately
Separate delivery. Rights object packing.
my $rights = $drm->separate_rights($permission, %constraint) # you have to send this rights object via WAP Push.
