Table of Contents
1. Introduction
Hash functions are essential for data integrity and security. They take input data and produce a fixed-size output.
2. What Is a Hash Function
A hash function is a mathematical function that converts input data of any size into a fixed-size string of characters.
3. Properties
Good hash functions are deterministic, fast, and produce unique outputs for different inputs (collision resistance).
4. Common Algorithms
Common hash algorithms include MD5, SHA-1, SHA-256, and SHA-512.
5. Use Cases
Hash functions are used for password storage, data integrity verification, and digital signatures.
6. Conclusion
Understanding hash functions is essential for building secure applications.
