Crypt::PBC::Pairing - OO interface for the Stanford PBC library
use Crypt::PBC; my $pairing = new Crypt::PBC("params_d.txt"); my $G1 = $pairing->init_G1->random; my $G2 = $pairing->init_G2->random->double->square; my $GT = $pairing->init_GT->pairing_apply( $G1, $G2 );
The only thing of use this package does is initialize elements in the pairing. It does many other things behind the scenes though.
my $G1_element = $pairing->init_G1; # returns Crypt::PBC::Element my $G2_element = $pairing->init_G2; # objects my $GT_element = $pairing->init_GT; my $Zr_element = $pairing->init_Zr;
The most important thing the Pairing package does is handle memory for you. The package is a scalar ref of the C-pointer.
$$pairing is the "address" as an integer!
It's important when clearing the PBC memory that pairings get cleared after elements and the Element and Pairing objects handle that on their own. You may safely ignore clearing elements and pairings if you use the OO interface.
