1. What is it Symmetric encryption refers to the use of the same key for both encryption and decryption. The process of encryption and decryption is illustrated in the following diagram: Symmetric encryption algorithms have the advantages of fast speed and high efficiency, but they face challenges in key distribution and are susceptible to eavesdropping. … Read more
Symmetric encryption can be divided into block ciphers and stream ciphers. Block ciphers typically use a fixed size as the basic unit for processing, while stream ciphers use a single unit element (a letter or a bit) as the basic processing unit. Of course, when the block length is equal to the unit length, a … 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

Introduction Hello everyone! If you are interested in encryption algorithms, then the DES algorithm is certainly a topic you cannot avoid. DES is like the classic sports car of the encryption world—debuting in 1977, it once enjoyed great popularity. Although it is no longer the safest choice today, DES remains a very interesting and useful … Read more
Ransomware is a new type of virus trojan that has emerged alongside the rise of digital currencies. It typically spreads through various forms such as brute force cracking, exploiting vulnerabilities, spam emails, and bundled software. Once a machine is attacked by ransomware, most files will be modified by encryption algorithms and have a special suffix … 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
