The SSL In OsCommerce Guide For The Innocent

Recommended Posts

What is (or Isn't) SSL ?

 

SSL stands for Secure Sockets Layer. This is technology derived in part from the military that encrypts data transfers across the internet. There are several flavours of SSL but the most prevalent one today is 128 bit encryption, but watch out 256 bit encryption is on it's way !

 

For an e-trader, SSL encryption protects your customers transaction details as they are passed back and forth between their browser and your server \ domain. The data encryption happens at one end using a key and is deciphered at the other end using an equivalent key. The permutations for how data can be encrypted are astronomical making it virtually theft and interference proof during transit.

 

SSL DOES NOT PROTECT your server from attacks, nor your admin or catalog from malicious hacks. In order to protect your server and files you need to use facilities such as firewalls, virus checkers, Apache and IIS user and password protection for directories and files.

 

Why Do I Need SSL ?

 

You need SSL if you are selling to the public for two very good reasons.

 

1) Your customers expect it - As surfers become more sophisticated they look at your site and want to make sure their details will be safe should they order products. SSL seals are part - but a big part - in that re-assurance process. If the choice between two sites comes down to which offers transaction security - do you want to be the site that misses out ?

 

2) Even if you have unsophisticated customers who do not look for SSL encryption before they buy - if the data they send you is intercepted and misused - you could land up being in heavy lawsuits for amongst many other things negligence. This is a small possibility - but do you want to take the risk ?

 

How Does SSL Work With OsCommerce ?

 

The workings of SSL with osCommerce are quite straightforward.

Once your SSL is installed - see sections below, you set the configuration paths for https:// in catalog/includes/configure.php and admin/includes/configure.php, enable SSL and the code takes care of the rest.

 

If you look through the code you will see example after example of statements that refer to SSL where osC is making a decision based on request type as to whether to display the secured or non secured pages.

 

In short neither you nor your customers has to type in https:// into the address line to get to secure pages. osCommerce will identify from the configuration if SSL is installed and direct browsers to the correct page depending on what the browser is doing on your site.

 

How Do I Get SSL ?

 

1) Surf and find a Certificate issuer you feel happy with where you buy your SSL cerificate for a period of time 1 year, 2 year etc etc)

 

Things to look out for are

 

a) They own or have a trusted root in most browsers.

 

All browsers come pre-installed with so called Trusted roots.

 

These prevent Joe Shmoe and his cousin Joe Bloggs from issuing worthless certificates that cannot do the encrypting to unsuspecting buyers.

 

To see trusted roots if you use IE go to Internet Options under tools and select the content tab where you will see in the middle section all the trusted root certs installed on IE and their issuers.

 

b ) If they don't have a trusted root in most browsers make sure they have a cert known as a chaining cert that links whatever they sell to you with a trusted root.

 

What is the difference -

 

Trusted root sellers are EXPENSIVE and very well recognised brands.

 

Chaining certs are affordable - They are still 128 bit encryption hence no less secure - but the brands are less well known.

 

2) Get your host to raise a CSR (Certificate Signing request) - To do this the host will need certain information from you, especially if they are not also your registrar. Such info will be your domains registered admistrator. This info will be required by the SSL issuer. Along with the CSR they also generate a key that will be used to encrypt and decipher data transmissions from your server \ domain. -

 

Things to look out for are

 

Your certificate will encrypt data in a very precise way - if the cert is issued to www.yourdomain.com it will NOT encrypt transfers between yourdomain.com and browsers and vice versa.

 

So make sure you instruct your host to get the CSR raised with the correct AND full name of the domain you want to be encrypted.

 

I normally use the domain name without the www. qualifier because servers for a number of reasons can strip the www. off, but I have yet to see a server add it on without a deliberate redirect.

 

3) Send the CSR to your cert issuer who will vet the details and write to the administrator noted when the CSR was raised.

 

4) Assuming you are the administrator of your domain - you will have to acknowledge the mail from the issuer and OK the SSL.

 

5) The issuer will raise a SSL cert and send it to you. If you are using a chaining issuer they will also send a chain certificate.

 

6) Send these to your host who will install as follows :

a) The SSL cert will be installed in a directory on your server along with the chaining certificate if applicable.

b ) They will also instal the key they generated in step 2 above.

c) They will then add certain statements known as directives to your Apache configure files. These tell Apache that the site has SSL encryption certification.

 

Making SSL Work With The Catalog and Admin

 

In order to make SSL work with osCommerce you need to set the correct configuration paths in

 

a) catalog/includes/configure.php

 

// Define the webserver and path parameters

// * DIR_FS_* = Filesystem directories (local/physical)

// * DIR_WS_* = Webserver directories (virtual/URL)

define('HTTP_SERVER', 'http://www.yourdomain.com'); // eg, http://localhost - should not be empty for productive servers

define('HTTPS_SERVER', 'https://yourdomain.com'); // eg, https://localhost - should not be empty for productive servers

define('ENABLE_SSL', true); // secure webserver for checkout procedure?

define('HTTP_COOKIE_DOMAIN', 'www.yourdomain.com');

define('HTTPS_COOKIE_DOMAIN', 'yourdomain.com');

define('HTTP_COOKIE_PATH', '/catalog/');

define('HTTPS_COOKIE_PATH', '/catalog/');

define('DIR_WS_HTTP_CATALOG', '/catalog/');

define('DIR_WS_HTTPS_CATALOG', '/catalog/');

 

b ) admin/includes/configure.php

 

// Define the webserver and path parameters

// * DIR_FS_* = Filesystem directories (local/physical)

// * DIR_WS_* = Webserver directories (virtual/URL)

define('HTTP_SERVER', 'http://www.yourdomain.com'); // eg, http://localhost - should not be empty for productive servers

define('HTTP_CATALOG_SERVER', 'http://www.yourdomain.com');

define('HTTPS_CATALOG_SERVER', 'https://yourdomain.com');

define('ENABLE_SSL_CATALOG', 'true'); // secure webserver for catalog module

 

* Note the assumptions above - The certificate was issued WITHOUT the www. qualifier and this shop is installed in Catalog directory ONE level below root.

 

In normal working - these changes above will result in a small padlock being shown in the bottom right of your browser status bar when you navigate to a secure page AND your address line will show the https:// URL instead of http://

 

Trouble Shooting

 

1) Security Alert

 

The alert box says info you exchange with this site cannot be viewed or changed by others. However there is a problem with the sites security certificate.

 

The box has 3 levels of alert

 

a) The certificate is from a trusted certifying authority - Green tick for good or Red cross for bad will show

b ) The security certificate date is valid - Green tick for good or Red cross for bad will show

c) The name on the security certificate is invalid or does not match the name of the site - Green tick for good or Red cross for bad will show

 

If the problem is a) then you need to take account of How Do I Get SSL point 1 above !

If the problem is B ) you need to extend the certificates validity - refer to the issuer.

If the problem is c) Your certificate has probably been issued with or without the www. and you have used the other spellng in your configure files. Make sure the cert name as issued is used in the configure.php files. (See How Do I Get SSL point 2 above)

 

2) This page has both secure and insecure items

 

This alert appears if the secured page the browser is trying to show has objects or references that point to non secured domains.

 

So for instance if you had a graphical image of credit cards as processed by your gateway and say you were hotlinking to the images with a piece of code such as <img src="http://mycreditcardprocessor.com.....> That image is not on your encrypted domain hence the alert would show.

 

Often this problem will appear from one or more of three sources

 

a) Where you are hotlinking images for your products from the wholesalers server

b ) objects in your footer

c) objects in your boxes in the columns

 

3) Page 404 (unavailable)

 

If you set your site up and during instal you choose SSL security WITHOUT having done the stuff in here you may get 404's when you try to access secured pages.

 

Wrapping Up

 

1) Self issued certificates

 

Some people have dedicated servers and even on some shared server you can raise a self issued SSL certification. This does everything as above except the certificate root does not exist in browsers. Therefore your site may be secure (although I do not profess to know if self certificates offer 128 bit encryption), BUT your site visitors will ALWAYS get the alert in Trouble Shooting point 1.

 

Even though the alert says the site is safe, this is perhaps worse than not having a certificate as it alerts people to the fact that there is a problem with the certificate - and people do not like problems !!!

 

2) Shared SSL certificates

 

Talk to your host for the path you need to apply in your configure.php paths

This page has both secure and insecure items

 

Ok, if the problem is say, the footers, how does one go about fixing it?

 

 

If the problem is an image you are hotlinking :) you need to ask the owner if you can have access to the image - place it in your own images directory under the encrypted domain and then change the path in your footer so that it now references the image in your domain.

 

If you have for instance a visitor counter that goes back to the counter owners server to process info - you may be able to construct an if else statement around the counter using php such that if the $request_type is SSL then do not go to the counter owners site.

 

I am not a PHP coder, but in one of my stores I have google ads and in order to show these the script has to go back to google - not on my domain - therefore problem

 

So I use the following construct to prevent google ads from showing iF the browser is on a secure page

 

<?php

if ($request_type != 'SSL') {

.....

.....

.....

src="http://pagead2.googlesyndication.com/pagead/show_ads.js">

</script>

.....

.....

}

?>

Thanks Charles

 

Very informative thread and have put it on "track"

I am sure this will help me out when i come to installing SSL.

 

Am looking at going with thawte, anybody else use them, good or bad?

 

Cheers

Hi Mike

 

Your named issuer is a heavyweight in the SSL world. But their technology is not necessarily better \ stronger \ more effective than a chaining cert issuer - as long as they also use 128 bit encryption.

Yes Charles, it is a good thread and thanks for posting it.

 

Personally I would not advise anyone to go with a chained ssl cert. I know they are cheap but the providers themselves say they are only suitable for low-usage sites with no more than 3-4 users in the https areas on the site at any one time. I think most web owners will aspire to having more users than that. With full ssl's costing only $39 a year it's not worth going down the chained ssl root.

 

Two things to point out - some hosts will not allow you to install ssl with them, and on a shared server you will need to also have a dedicated ip address to run a full ssl cert.

Does this apply to regular (non-image) links too?

For example, when you're checking out you still see the product categories

and links on the left (catalog). Links seem to point to non-SSL page.

 

 

Someone recommended I move my entire site to SSl, but I'm afraid it will

increase the load too much and make it slow.

As long as the links are on www.yourdomain.com this should not be a problem.

 

The problems arise when you have anything that looks like <a href="http://www.notmydomain.com...> or <img src="http://www.notmydomain.com...>

Excellent thread Charles.

 

If I'm not mistaken. Aren't the <a href="http://www.notmy domain.com...> tags fine? You are not accessing anything else with that code. You are just setting up a link. Now, if you had a ...src="http://www.notmydomain.com/images/someimage...."> in that tag or in a css file that the tag uses, then that would cause a problem.

 

Another problem I came across that I haven't seen much is the <link > tag. Watch what is put in there. It will cause the same problem.

 

Again, very helpful thread.

all three work well, the instant certificate works, but does not validate to your merchant account that you are who you say you are. you have to go with the next step up to have the validation.

The problem of getting a security message is because of the http bit in the URL. As soon as you go to a secure page this will change to https and any images that are linked as http://www.somethingorother.com will cause the security message to be displayed.

As Charles says if you remove the http bit and just link to www.somethingorother.com it will be fine.

did you install the cert yourself on the server ?

 

Your config looks wrong at first glance - the http server should have www. as a prefix and the https server path should be in the full name as issued on your cert which may or may not include the www.

 

also make sure your cookie domains are configured with the correct names as in my original post and in relation to your issued cert name

stupid question time.

 

can I buy one SSL certificate and use it on two different sites?

 

An SSL cert will generaly protect (encrypt) data from a single domain.

 

A so called wild card SSL cert will additionally protect all subdomains of that domain.

 

So in brief the answer to your question is no

I don't understand what u mean about the cookies? and what do you mean full name on the CERT? how do i figure out if I did that right? do you know how to do install a cert on CPANEL?

Having problems when I secure my Admin via SSL...it works but in certain areas it will log me off and I have to log back in (I have the Administration Access Level Accounts 2.0 contribution installed). For example, when I am on the customer page and try to search for a customer, it logs me out of my admin session.

 

Let's assume my website url is: www.abccompany.com

and i have a shared SSL certficate: https://id100.securedata.net/abccompany

 

Here are my current settings:

 

define('HTTP_SERVER', 'https://id100.securedata.net/abccompany'); 
define('HTTP_CATALOG_SERVER', 'https://id100.securedata.net/abccompany');
define('HTTPS_CATALOG_SERVER', 'https://id100.securedata.net/abccompany');
define('ENABLE_SSL_CATALOG', 'true'); 
define('DIR_FS_DOCUMENT_ROOT', '/www/abccompany/');  
define('DIR_WS_ADMIN', '/admin/'); // absolute path required
define('DIR_FS_ADMIN', '/www/abccompany/admin/'); 
define('DIR_WS_CATALOG', '/'); 
define('DIR_FS_CATALOG', '/www/abccompany/');

 

and suggestions would be much appreciated. Thanks!

Post both your configure.php files for review - I think your cookie paths are wrong .
