I am trying to create a QR code with some simple text in it since the text has some personal info in it I should encrypt it.
Can anyone explain to me how to actually use the Cryptography blocks?
I can create and read the QR code correctly with simple text in it. But if I encrypt text, use it to generate a QR code. I cant then decode the text, all it returns is an empty string.
Thank you very much in advance.
