I unsuccessfully tried solving it on my own. Then I searched the web about AES, but it seems impossible to decrypt and it is overall confusing. Am I missing something? Am I just not trying hard enough? Thanks for your attention.
I was also clueless about this level at first but after I solved some other challanges on other sites the mist started to disappear. Just try to understand the pattern and try to understand how low level encryption is done.If there is any spoiler in my reply pls notify me.
