Decryption effect

[StarDate1]

Dear author, when I reproduced your code, I found that there are always some undecrypted parts on the left edge of the image (I showed the decrypted image). I am a scholar who has just touched this field. How can I solve this problem?

You might want to try limiting the key value to 6 digits and see if that resolves the issue. This adjustment could help ensure that the decryption process works correctly across the entire image. Give it a shot and let me know if it helps.

引用回复 Thank you very much for your reply. I followed your suggestion to limit the key value to 7 digits (because it is easier to change it according to the original logic). But the result did not change, and the undecrypted pixels still appear on the left. Maybe I changed it wrong? I hope you can answer me when you are free. I am sorry that I can only take a screenshot to show you my code, GitHub does not support uploading .py files. And I attached my decrypted picture again.
