Comment on Rewriting for SEO-Friendly URLs: .htaccess or PHP? by Anton Oliinyk

Yes, you’re right. Definitely some way is needed to establish a match between human-friendly URL directory names and database records. So “slug” fields do.
The only little difference in this particular sample case is that product slug have to be unique within category only as we use both category and product slugs to find a product. So there could be products with the same slug in other categories.

Hi.
So I figure the slug field would be the same thing has the numeric ID field, only that contains words.
Making sure there are no duplicate slag names also.
Ill give it a try.

Thanks for the example.

Say, category table is:
id, slug, label
1, appliances, Appliances
2, network, Network
3, video, Video
…

And product table is:
id, category_id, slug, label, description
1, 1, blender, Blender, This is cool blender
2, 1, water-filter, Water Filter, This is cool water filter
3, 2, router, D-Link DIR-300, This is not so cool network router
…

Now you get request for /products/network/router.html
which is rewritten to products.php?category=network&product=router

Now let’s query product data:
$rs = $db->query(" SELECT `product`.* FROM `product` JOIN `category` ON `product`.`category_id` = `category`.`id` WHERE `product`.`slug` = '{$db->real_escape_string($_GET['product'])}' AND `category->slug` = '{$db->real_escape_string($_GET['category'])}'");

The result set will contain single record for the product with ID 3.

Hope that helps.

Hi!
You’ll have to query database using string IDs you use in URLs. Say, you can add a field ‘slug’ to category and product tables and look up records by that field.

Hi,
Thanks for sharing this.
I have some questions I hope you can clarify.

I normally user rewrite mod with the unique numeric ID of the information I need, in order to query the mysql database.
With your example there is no numeric ID.
Now I’m confused
There is where my questions start.

Imagine I have a product
products.php?category=network&product=1
products.php?category=network&product=2

How can I make
/products/network/router.html open products.php?category=network&product=1
and
/products/network/cable.html open products.php?category=network&product=2

Thanks in advance

Comment on Reading, writing and converting RSA keys in PEM, DER, PUBLICKEYBLOB and PRIVATEKEYBLOB formats by Anton Oliinyk

Hi! This is actually W3C standard format for RSA keys: http://www.w3.org/TR/xkms2/ (find 8.2.1 for descriptions of elements).
The numbers like modulus and exponent, etc are base64 encoded.
Hope that helps.

I land here because I want to convert a Private key to XML.

OK. I was also shocked, “PKCS8 to XML, please give me a break” I think.

Well, it happens that some web service I am trying to consume ask me for that sort of thing, and I discover there’s actually some .NET library that requires such structure :

[RSAKeyValue]
[Modulus]1KHjZtqkEv1ECT…X8bnZk=[/Modulus]
[Exponent]AQAB[/Exponent]
[P]9g3MtFSVVE…bm68+HIobw==[/P]
[Q]3To87MOrKL7RvKP…RFdOdw==[/Q]
[DP]jXOpdxIZNvrcJ7RiKff..+0c6Q==[/DP]
[DQ]VlB8qNwHEdSxvGoi2np..3mLQ==[/DQ]
[InverseQ]EtwABGpy/cumIxHI5..RMvWmQ==[/InverseQ]
[D]PEg5RCuwYIHVDBgVcWeXD9q6TsUQ..m0mIrRXJQABE=[/D]
[/RSAKeyValue]

(data was broken to be more readable)

I still can´t get this XML done in my programming but with the information you post it will be a snap thing to do. Thanks.

PLEASE NOTE, LESS THAN AND GREATER THAN HAS BEEN REPLACE BY SQUARE BRACKETS, sorry for the inconvenience and the re-post

Hi!
Surprisingly, another guy recently contacted me and suggested using native CryptoAPI functions for key conversion. According to his findings CryptStringToBinaryA function can decode PEM to DER.
Please find “Update…” section I added to the bottom of the post.
