A hash function is a mathematical function that takes an input (or “message”) and returns a fixed-size string of characters, which is typically a hexadecimal number. It’s commonly used in cryptography and data verification.
Example: A simple example of a hash function is the MD5 hash function, which takes an input and produces a 32-character hexadecimal output. For instance, the MD5 hash of the string “Hello, World!” is “65a8e27d8879283831b664bd8b7f0ad4.” Hash functions like MD5 are used to verify data integrity and create digital signatures, among other applications. However, MD5 is considered weak for security purposes today due to vulnerabilities, and more robust hash functions like SHA-256 are often used in cryptography.
