Auth::Yubikey_DecrypteUser Contributed Perl DocumentAuth::Yubikey_Decrypter(3)

NAME
       Auth::Yubikey_Decrypter - Decrypting the	output from the	yubikey	token

VERSION
       Version 0.07

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";

FUNCTIONS
   yubikey_decrypt
       Input : token aeskey

       Token - received	by the Yubikey aeskey -	either the modhex or hex AES
       key for your Yubikey (contact Yubico if you don't have the AES key)

       Output :

       $publicID $secretid_hex $counter_dec $timestamp_dec $session_use_dec
       $random_dec $crc_dec $crc_ok

   yubikey_modhex_decode
       Input : the modhex code Output :	decoded	modhex code in hex

   yubikey_crc_check
       Performs	a crc check on the decoded data

REQUIRES
       Perl 5, Crypt::Rijndael

       Order your Yubikey from <http://www.yubico.com>
