"Decode the image and submit the flag in less than 6 seconds."
What kind of a flag am I suppose to submit? I decode the image in less than 1 second and submit the text the same way I did in the "CAPTCHA me if you can" challenge. However, I get the new page with the new image and the sentence: "Missed, retry your chance."
Is there a catch somewhere that I cannot see? The decoded text does not seem to be encoded with anything and looks legitimate.
Regards.

Never mind. 10 minutes later I did it. "It’s always the darkest under the lighthouse". The key is the flag :)

Hi!
I have difficulties decoding the QR (after adding finder patterns). Decoding with my android barcode scanner is no problem, but zbar and zxing fail, any suggestions?

How do you fix the QRcode from the base64 string? I tried comparing the provided base64 string and the base64 of an "only corners" QRcode image, but I don’t know if this is the good way...I imagine that the base64 string needs to have a particular order to reconstruct the QRcode image. Is there another way to do it?
