The main purpose of a hash is to uniquely convert data of any size into a fixed size, creating a digital fingerprint. It ensures data integrity; a single change in the input drastically changes the hash, revealing tampering. Hashes are critical in various applications like password storage, data verification, and ensuring data security.

FAQs & Answers

  1. What is a hash function? A hash function is a mathematical algorithm that converts input data into a fixed-size string, known as a hash, used for data integrity verification.
  2. Why are hash functions important for password storage? Hash functions ensure that passwords are stored securely by converting them into a unique hash value, making it difficult for attackers to retrieve the original password.
  3. How does tampering affect a hash? Even a slight change in the input data results in a completely different hash, allowing detection of any unauthorized changes.
