Introduction In the field of computer security, encryption algorithms are one of the key technologies for protecting data integrity and privacy. Among them, MD5 is a widely used hash algorithm, and this article will introduce several use cases of MD5. 1. What is MD5? MD5 is a one-way hash function used to convert input data … Read more
1. Basic Concepts MD5 (Message-Digest Algorithm 5) is a widely used hash function that generates a 128-bit (16-byte) long “digital fingerprint” or hash value for each different file. This hash value can be seen as a unique identifier for the file, similar to an ID number. Its core function is to verify the integrity and … Read more
Application of C Language in Blockchain Technology: Underlying Implementation Blockchain technology has become a focal point in recent years, characterized by decentralization, immutability, and transparency. While many modern programming languages (such as Python, JavaScript, etc.) are widely used in blockchain development, C language still plays a significant role in some underlying implementations due to its … Read more
Hash Tables and Hash Functions in C++ In computer science, a hash table is a data structure used to implement an associative array or set, which maps keys to buckets or indices using a specific function called a hash function. Hash tables provide fast data access speeds, making them widely used in many applications. 1. … Read more
