Tired of the same old dreary Security Graphic?

Raven · Posted: Wed Oct 29, 2003 8:06 am

Tired of the same, dreary old security code? Well, try this code. You can modify it to your heart's content! If you create something really neat, nice, pretty, etc., please post it back! Note that it needs no images and it is using JPG, but can easily be modified to PNG or any other format.

Code:

function gfx($random_num) {
global $prefix, $db;
require("config.php");
$datekey = date("F j");
$rcode = hexdec(md5($_SERVER[HTTP_USER_AGENT] . $sitekey . $random_num . $datekey));
$code = substr($rcode, 2, 6);

$circles=5;
$width=100;
$height=40;
$font=5;

$fontwidth = ImageFontWidth($font) * strlen($string);
$fontheight = ImageFontHeight($font);

$im = @imagecreate ($width,$height);
$background_color = imagecolorallocate ($im, 255, 255, 255);
$text_color = imagecolorallocate ($im, rand(0,100), rand(0,100),rand(0,100)); // Random Text

for ($i=1;$i<=$circles;$i++) {
$randomcolor = imagecolorallocate ($im , rand(100,255),rand(100,255),rand(100,255));
imagefilledellipse($im,rand(0,$width-10),rand(0,$height-3),rand(20,70),rand(20,70),$randomcolor);
}

imagerectangle($im,0,0,$width-1,$height-1,$text_color);
imagestring ($im, $font, 12, 12,$code,$text_color);
header ("Content-type: image/jpeg");
imagejpeg ($im,'',80);
ImageDestroy($im);
die();
}

cool, can we see it in action Smile

Raven · Posted: Wed Oct 29, 2003 8:44 am

Sure. Just replace your gfx() function in modules/Your_Account/index.php Smile

and/or admin.php. You think I'm going to do EVERYTHING for you people? Laughing

scottr · Posted: Wed Oct 29, 2003 8:49 am

Don't you already ? hehe. Laughing

I don't have GD loaded at home and i got everything working
and don't want to risk breaking things.
Actually i would like GD loaded here.

Ah the wonderful world of randomization functions Laughing

What would be causing this. It isn't a major issue, just wondering if I can remedy the problem.

Code:

PHP Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/froggerz/public_html/admin.php on line 149

Code:

Line 149 ImageDestroy($image);

Raven · Posted: Thu Oct 30, 2003 9:14 am

Did you remember to change your JPG to PNG logic? I think you would change

Code:

header ("Content-type: image/jpeg");
imagejpeg ($im,'',80);

to

Code:

header ("Content-type: image/png");
imagepng ($im,'',80);

This should work with 6.9 right?

(getting tired of being high maintnance but my admin is broke now and I can't log in)

how do you control the size of the image if I have it set on my default theme to a certain size

Well, it works with my 6.9

TheosEleos · Posted: Thu Oct 30, 2003 9:32 pm

I give up, on all of this. I'll cut loose so you can have a break from me. See you in a couple of weeks. Sad

Frogger · Worker Joined: Oct 06, 2003 Posts: 108

Works for me in 6.8, 6.9 and 7.0 beta

Frogger · Worker Joined: Oct 06, 2003 Posts: 108

Anyone know what is causing this:

Code:

PHP Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/WWW/public_html/admin.php on line 149

Raven · Posted: Fri Oct 31, 2003 8:50 am

I think this line

Code:

ImageDestroy($image);

should be

Code:

ImageDestroy($im);

I corrected my original post - SORRY!

Not a fo-pah? Laughing

THANKS for this code hack info "Raven"!! I've been trying to figure this one out for a while!

Why would you ant it soo hard to read? That's one of the things I hate about ordering tickets on ticketmaster - some of their images aren't readable.

Well, I have to take extra security precautions since I co-locate my server at work (I happen to work at a local ISP) & I'm getting free unlimited bandwidth. I just can't abuse that now can I? Wink

So you just want the checkerboard background? If so, why not just use the one that comes with nuke?

NOPE.....I wanted something different than the plain security code that comes with nuke!! Like the code you posted earlier in this topic, but I was also wondering if there's a code hack to make it look similar the one on the

Their's has randomly generated background images & words (it can be seen if you refresh the page a couple of times)!! Confused

Hey....I've found another way to customize the security code, in addition to Raven's suggestions!! Razz

:
yeah i made something similiar for 6.7 (should work on 6.8 but will break 6.9& up security code on/off switch)

(refresh a few times)

Turn on/off security images for user login, user registration, and admin panel
specify the length of the code (3-10)
use "Enhanced" security codes similiar to those found on major sites like
yahoo!
aol IM
Hotmail

Create you own security code graphics
