The challenge gives 2 files - [image](https://github.com/mar232320/ctf-writeups/blob/main/wreck2022/barcode/output.png) and a [script](https://github.com/mar232320/ctf-writeups/blob/main/wreck2022/barcode/encode.py) used to create it
Every black stripe in the image is of the same height but different widthThe width is always multiple of 16I found the positions where black changes into white - the starting and ending points of stripesEvery white is a 0 bit and black is 1
I made a [script](https://github.com/mar232320/ctf-writeups/blob/main/wreck2022/barcode/solve.py) to get the flag
