There is an ongoing outage on the primary CPAN mirror. It is possible to work around the issue by using MetaCPAN as a mirror.

NAME

Digest::OMAC2 - OMAC 2 implementation

SYNOPSIS

use Digest::OMAC2;

my $d = Digest::OMAC2->new( $key, $cipher );

DESCRIPTION

OMAC 2 is a variant of the CMAC/OMAC 1 algorithm. The initialization routines are slightly different. OMAC2 actually precedes OMAC1, so Digest::CMAC/Digest::OMAC1 is the reccomended version. Supposedly OMAC1 was more rigorously analyzed.
