QUESTION

PDF417 decode and generate the same barcode using Swift

Asked 2021-Mar-07 at 10:01

I have the following example of PDF417 barcode:

which can be decoded with online tool like zxing

as the following result: 5wwwwwxwww0app5p3pewi0edpeapifxe0ixiwwdfxxi0xf5e�¼ô��¬‚C`Ìe%�æ‹�ÀsõbÿG)=‡x‚�qÀ1ß–[FzùŽûVû�É�üæ±RNI�Y[.H»Eàó¼åñüì²�tØ¿ªWp…Ã�{�Õ*

or online-qrcode-generator

as 5wwwwwxwww0app5p3pewi0edpeapifxe0ixiwwdfxxi0xf5e~|~~~~~~~~~~d~C`~e%~~~~;To~B~{~dj9v~~Z[Xm~~"HP3~~LH~~~O~"S~~,~~~~~~~k1~~~u~Iw}SQ~fqX4~mbc_ (I don't know which encoding is used to encode this)

The first part of the encoded key that contains barcode is always known and it is 5wwwwwxwww0app5p3pewi0edpeapifxe0ixiwwdfxxi0xf5e

The second part of it can be decoded from the base64string and it always contains 88 bytes. In my case it is:

CIPDF417BarcodeGenerator has a few more input parameters besides inputMessage that can have an influence on how the generated barcode looks - see the documentation. Visual inspection/comparison of two codes only makes sense when you know that all these parameters, most importantly inputCorrectionLevel were equal for both generators.

So, instead of a visual comparison, simply try decoding the barcodes using one of the many scanner apps out there, and compare the decoded bytes.

For your second example, try this:

QUESTION

crypto.getRandomValues() not supported

Asked 2020-Apr-20 at 17:52

I'm getting this error with npm react-native-webview@9.0.1 when I try to generate a QR code with react-native-qrcode-generator

I'm using react-native with an expo managed workflow. And the thing is it works on iOS, and i only get the error on Android

I searched for a solution myself and I tried installing react-native-get-random-values but that also didn't work.

Any thoughts?
