NAME

Auth::Yubikey_Decrypter - The great new Auth::Yubikey_Decrypter!

VERSION

Version 0.01

SYNOPSIS

The decryption module does only one thing - decrypt the AES encrypted OTP from the Yubikey. To this, it requires the OTP, and the AES key.

Please note - this module does not perform authentication - it is a required component to decrypt the token first before authentication can be performed.

	#!/usr/bin/perl

	use strict;
	use Auth::Yubikey_Decrypter;

	my $fulltoken   = "dteffujehknhfjbrjnlnldnhcujvddbikngjrtgh";
	my $aeskey      = "ecde18dbe76fbd0c33330f1c354871db";

	my ($publicID,$secretid_hex,$counter_dec,$timestamp_dec,$session_use_dec,$random_dec,$crc_dec,$crc_ok) =
        	Auth::Yubikey_Decrypter::yubikey_decrypt($fulltoken,$aeskey);

	print "publicID  : $publicID\n";
	print "Secret id : $secretid_hex\n";
	print "Counter   : $counter_dec\n";
	print "Timestamp : $timestamp_dec\n";
	print "Session   : $session_use_dec\n";
	print "Random    : $random_dec\n";
	print "crc       : $crc_dec\n";
	print "crc ok?   : $crc_ok\n";
