[Day 04] Grinding PicoCTF 2

Preface

Family, family! In view of the two news I received yesterday, the first is that there will be CTF playoffs for the SCIST Cybersecurity course from 7/10 to 7/12, and the second is that I have been admitted to the AIS3 summer Cybersecurity course, so I decided to first Let’s brush up on some questions. So [this: The Meridian of Cryptography](/StudyNotes/Cryptography-Notes-: The Meridian of Cryptography) I will take it slow first, and then I will add it after the competition is over! ! !

#Today’s progress

I wrote three questions this afternoon, one question each on Misc, Crypto, and Forensics. I learned a lot of new knowledge! It really becomes more interesting the more you learn, I love learning! Learning makes me happy! I deeply understand the pleasure that knowledge can bring to My, which is a deeper happiness.
