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
Before reading this chapter, please first understand the theory of encoding and decoding in computer basics and an introduction to OpenSSL.What is the relationship between binary, hexadecimal, bytes, and strings? HTTPS, certificates, data encryption… How many of these OpenSSL skills have you used? Below is the main content Encryption Algorithms In API integration, commonly used … 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

1. Definition of Asymmetric Encryption Algorithms An asymmetric encryption algorithm is a type of encryption technology that uses a pair of keys for encryption and decryption. Unlike symmetric encryption, asymmetric encryption uses two keys: a public key for encrypting data and a private key for decrypting it. Only the recipient who possesses the private key … Read more
1. Definition of Symmetric Encryption Algorithms A symmetric encryption algorithm is a type of encryption technology that uses the same key for both data encryption and decryption. In simple terms, the sender and receiver must share the same key, which is used to encrypt and decrypt the data. Symmetric encryption is often used in scenarios … Read more
