Doesn't presume the viewer to be an idiot or a genius or fill the videos with fluff. It's hard to find anything like it. I learn more about python watching him dissect it in one video than anything else in several
Ciphers are incredibly common in cryptography, it's just that they're usually combined with multiple other methods to further obfuscate the data. NES games used bitshifting and XOR in their passwords, for example. With a simple substitution cipher, to show the player the resulting data in a human-readable way. So, it could be written down, for later.
I was such a dumb guy, instead of python replacing all the strings what i did was print the index and value of that 'a' string and i manually found and replaced it. Such a dumb way to do it.
It's in one of the first picoctf videos. There was some easy challenge and time left so he created 2 scripts in bash. I think the save script saves the flag in flag.txt, if I remember correct , and finish adds _COMPLETED to the the directory name so you know the challenge is completed. You don't need those scripts to finish a challenge, they are his own quality-of-life scripts. But you'll learn some scripting watching this video
It seems to me, that approximately 99.999% of the Python Code i get or see looks like the obfuscated CTF-File. And always this is just the pythonic way to do things. With loads of comments like "// get np for xxx" because everyone knows that np means numpy, right? Anyway.... i like Python as a Programming language... most programming styles of this language i strongly dislike. Also: nice video
It’s “how do they look” or “what do they look like.” Not “how do they look like.” That’s an English mistake that foreigners make, and that now native English speakers are starting to become corrupted by.
