Implementing Graphs with Adjacency Matrix and Adjacency List in C In data structures, a graph is a very important model that can represent various relationships, such as social networks, maps, and transportation networks. Graphs can mainly be represented in two ways: the adjacency matrix and the adjacency list. This article will detail these two representation … Read more
In the field of information security, cryptography plays a crucial role by encoding and decoding information to ensure its confidentiality, integrity, and authenticity. Symmetric encryption is a major branch of cryptography, characterized by the use of the same key for both encryption and decryption. Among the many symmetric encryption algorithms, the Advanced Encryption Standard (AES) … Read more
In Java development, data security is of utmost importance, and the Java Cryptography Architecture acts as a reliable “security guard,” providing various encryption algorithms to ensure data safety. Below, I will guide you through how it meets the needs for data encryption and security authentication. 1. What is the Java Cryptography Architecture? Let’s first discuss … Read more

It is well known that the stability of the world’s financial infrastructure relies on the RSA encryption algorithm used by banks. This algorithm ultimately hinges on the difficulty of prime factorization. Since factorizing large numbers is a challenging task, almost impossible to accomplish manually, even computers would take thousands of years to crack a large … Read more
This article introduces commonly used cryptographic algorithms in daily development. abstract.png Classical Cryptography Classical cryptography typically employs simple techniques such as substitution (replacing letters in plaintext with other letters) and transposition (rearranging the order of letters in plaintext), without the need for complex machines or algorithms. Therefore, its security is insufficient and easily compromised. Caesar … Read more
