Barcodes van statiegeldflessen

Posted by jpluimers on 2025/05/29

Het overkomt te vaak dat barcodes beschadigd of overplakt zijn (hallo Too Good to Go, hallo “samen minder verspillen” van Jumbo en vergelijkbare acties)

Daarom wat barcodes van producten die je er overheen kunt plakken:

CyberChef: The Cyber Swiss Army Knife – a web app for encryption, encoding, compression and data analysis.

Posted by jpluimers on 2022/06/23

[Wayback/Archive.is] CyberChef:

a simple, intuitive web app for carrying out all manner of “cyber” operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

Via [Archive.is] Jilles🏳️‍🌈 on Twitter: “Hidden in plain sight. Rot13 cross word. Hidden Barcodes. Qr codes. Barely any InfoSec skill required. Still a hand full. Usually my to go place is: Cyberchef. I did a fun one for cyberklaas using ansi art.… “

Jilles also pointed to the solving part in [Archive.is] Jilles🏳️‍🌈 on Twitter: “See also, for solving: SCWF… “

The [Wayback/Archive.is] Solve Crypto with Force! needs to run without most script blockers, so best run it in an anonymous/private browser window.

Source code for SCWF is at [Wayback/Archive.is] DaWouw/SCWF: CTF tool for identifying, brute forcing and decoding encryption schemes in an automated way.

Home – Outpan – GTIN to product attribute mapping

Posted by jpluimers on 2018/04/26

On my research list: Home – Outpan as it is a key-value store of EAN (actually GTIN, so including GS1 UPC, EAN which means barcodes like UPC-12, EAN-8, EAN-13 and ITF-14).

  • [WayBack] Global Trade Item Number – Wikipedia
  • [WayBack] API Documentation – Outpan Developers

    Legacy API

    Get Product Information

    GET https://api.outpan.com/v2/products/[GTIN]?apikey=[YOUR API KEY]

    Add Product Name

    POST https://api.outpan.com/v2/products/[GTIN]/name?apikey=[YOUR API KEY]

    Required POST parameters:

    name: The name you would like to add for this product.

    Add Product Attribute

    POST https://api.outpan.com/v2/products/[GTIN]/attribute?apikey=[YOUR API KEY]

    Required POST parameters:

    name: Name of the attribute you would like to add for this product.

    value: Value for the attribute you would like to add for this product.

    • [GTIN] is the barcode number (ISBN, EAN, UPC, …) of the product you’re looking up.
    • All API calls must be done via HTTPS. Plain HTTP calls will be rejected.

Edit 20210402: this library has since moved without commit history from Google Code to GitHub with new source code file at [Wayback/Archive.is] yinyang/Ean13.php at master · henryhayes/yinyang.

YinYang Zend Framework Supplement Library

YinYang is a library of classes. Generally anything that is created in addition to Zend Framework and can be reused will be included in this library. YinYang requires Zend Framework as most of the classes extend ZF.

To use, simply checkout a copy, add the library/YinYang folder to your library folder and add YinYang to your list of autoloader namespaces.

Generating EAN-13 barcode EPS files for your article numbers

Posted by jpluimers on 2009/11/30

Recently, I needed a bunch of EPS files for EAN-13 barcodes (that’s the kind of barcodes European companies put on their products).

Edit 20250520: added Wayback/Archive links but some of the below links died, so at the bottom I have added additional pages and properly archived them.

[Archive] Terry  Burton wrote a great barcode writer in pure PostScript for this, with a simple [Wayback/Archive] web front end to generate a barcode one at a time.
