Kerckhoffs principle states that the security of a cryptographic system relies solely on the security of the key, with everything else in the system considered public information. However, in reality, software reverse engineering and dynamic/static debugging techniques have successfully executed key extraction attacks on cryptographic systems. Given this fact, both the industry and academia have … Read more
Encryption is generally about encrypting binary encoded formats, which corresponds to Python as Bytes. You need to convert str to Bytes using encode and decode. 01 md5 import hashlib def MD5(str): h1 =hashlib.md5() h1.update(str.encode(encoding = 'utf-8')) return h1.hexdigest() # lowercase if __name__ == "__main__": str ='123232' md5 =MD5(str) print("Before encryption: "+ str) print("After encryption: " … Read more

Experts can skip this; this is just a beginner’s learning note, not very substantial. The renowned AES has always been a concept I knew vaguely, but I didn’t understand its details well and often just skimmed over it. Recently, due to circumstances, I reluctantly started to delve into it… After learning about it, I found … Read more
1. Overview of Cryptographic Algorithms Cryptographic algorithms play a crucial role in today’s digital age. With the rapid transmission and storage of information, protecting data security and privacy has become a top priority. Cryptographic algorithms are mainly divided into three categories: symmetric encryption, asymmetric encryption, and hashing algorithms. Symmetric encryption algorithms are an early and … Read more
Source:http://dwz.date/afUd 1. Basic Concepts of Encryption “Encryption” is a technology that restricts access to data transmitted over the network. The original data (also known as plaintext) is encoded into ciphertext by encryption devices (hardware or software) and keys. The process of restoring ciphertext back to the original plaintext is called decryption, which is the reverse … Read more
