Qr Code With Encryption S’abonner

Okay, I have basically no idea what I'm talking about - besides knowing that Encryption is a way to protect data from viewing without a "key".

We have had a request come in that asks us if we are "able to generate a QR code image using data with Binary Encrypted coding". Anyone have experience with this? I assume we could custom calculate a field value in VB scripting, but I don't know if this is a common request or not for QR codes.

I countered that the end user should simply provide us with the data they wish to be encoded, and we'll link it via database connection. Still curious about this Binary Encryption though.

This link should be helpful.

The QR symbology in BarTender does allow for binary encoding of the data, but it doesn't support any built-in encryption. You could of course use VB script to perform the encryption on the string of data, but I don't know if you would need to conform to a standard such as the 56 bit DES encryption mentioned in the Wikipedia article. Seaching Google with a term, "encryption with VB script" should turn up a number of examples that you could possibly use in an OnProcessData script.

As of version 9.4 BarTender doesn't support raw binary data in barcode datasource (it doesn't accept NULL(0x00)as data).
So when storing binary data in QR code you need to encode data as ascii text such as [url="http://en.wikipedia.org/wiki/Base64"]Base64[/url] or hexadecimal, and reader application needed to decode that to raw binary after reading QR code.
(In RFID object you have option to store binary data.)

SQRC - Secure QR Code is not supported by BarTender.

Alright - so the customer is basically sending a string of Hex data. I found a script already to convert that Hex to CHR(xx) format - after which I put it into the QR code using binary encoding. I think I'm on the right path - just need to bounce the specs off the end user a couple times to be sure I'm getting it right. Thanks.
