[Algorithm](encrypt.py) is very hard and works too long. It codes every pixel into 64 bytes long hash and joins them into the one string.
It means, that we can just split [encrypted data](encrypted.txt) into [blocks of 64 chars](encrypted_splited.txt).
After calculating we can see that there are just 17 different hashs (pixels) there.
Now we can replace them by RGB-tuples and find the right image size, knowing the number of pixels in the image.
