VERSION

Version 3.00

SYNOPSIS

Authenticate against the Yubico server via the Web \s-1API\s0 in Perl

Sample \s-1CGI\s0 script :-

        #!/usr/bin/perl

        use CGI;
        $cgi = new CGI;
        $otp = $cgi->param("otp");

        print "Content-type: text/html\n\n";
        print "<html>\n";
        print "<form method=get>Yubikey : <input type=text name=otp size=40 type=password></form>\n";

        use Auth::Yubikey_WebClient;

        $id = "<enter your id here>";
        $api = "<enter your API key here>";
        $nonce = "<enter your nonce here>";

        if($otp)
        {
                $result = Auth::Yubikey_WebClient::yubikey_webclient($otp,$id,$api,$nonce);
                # result can be either ERR or OK

                print "Authentication result : <b>$result</b><br>";
        }

        print "</html>\n";

FUNCTIONS

new

Creates a new Yubikey Webclient connection

use Auth::Yubikey_WebClient;

my $yubi = Auth::Yubikey_WebClient->new({ id => <enter your id here> , api => '<enter your API key here>' , nonce => '<enter your nonce if you have one>' });

You can overwrite the \s-1URL\s0 called if you want to call an alternate authentication server as well :-

use Auth::Yubikey_WebClient;

my $yubi = Auth::Yubikey_WebClient->new({ id => <enter your id here> , api => '<enter your API key here>' , nonce => '<enter your nonce if you have one>', url => 'http://www.otherserver.com/webapi.php' });

debug

Displays the debug info

$yubi->debug();

Prints out some debug information. Useful to be called after authentication to see what Yubico sent back. You can also call the variables yourself, for example if you'd like to see what the token \s-1ID\s0 is, call $yubi->{publicid}. The same goes for all the other variables printed in debug.

yubikey_webclient

otp

Check a \s-1OTP\s0 for validity

$result = $yubi->otp($otp);

Call the otp procedure with the input from the yubikey. It will return the result.

This function will also setup a few internal variables that was returned from Yubico.

USAGE

Before you can use this module, you need to register for an \s-1API\s0 key at Yubico. This is as simple as logging onto <https://upgrade.yubico.com/getapikey/> and entering your Yubikey's \s-1OTP\s0 and your email address. Once you have the \s-1API\s0 and \s-1ID\s0, you need to provide those details to the module to work.
