Auth::Yubikey_WebClient - Authenticating the Yubikey against the Yubico Web API
Version 4.01
Authenticate against the Yubico server via the Web API in Perl
Sample CGI script :-
#!/usr/bin/perl
use CGI;
use strict;
my $cgi = new CGI;
my $otp = $cgi->param("otp");
print $cgi->header();
print "<html>\n";
print "<form method=get>Yubikey : <input type=text name=otp size=40 type=password></form>\n";
use Auth::Yubikey_WebClient;
my $id = "<enter your id here>";
my $api = "<enter your API key here>";
my $nonce = "<enter your nonce here>";
if($otp)
{
my $result = Auth::Yubikey_WebClient::yubikey_webclient($otp,$id,$api,$nonce);
# result can be either ERR or OK
print "Authentication result : <b>$result</b><br>";
}
print "</html>\n";
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>',
verify_hostname => 0 # optional - defaults to 1. Can be set to 0 if you do not want to check the validity of the SSL certificate when querying the Yubikey server
});
You can overwrite the URL 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'
});
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 ID is, call $yubi->{publicid}. The same goes for all the other variables printed in debug.
Check a OTP 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.
Before you can use this module, you need to register for an API key at Yubico. This is as simple as logging onto <https://upgrade.yubico.com/getapikey/> and entering your Yubikey's OTP and your email address. Once you have the API and ID, you need to provide those details to the module to work.
