What is a Hash?

A hash function takes input data and produces a fixed-size string of characters. It's a one-way function — you can't reverse a hash to get the original data. Hashes are used for data integrity, password storage, and digital signatures.

Hash Algorithms

• MD5 — 128-bit hash, fast but not secure for cryptography
• SHA-1 — 160-bit hash, deprecated for security use
• SHA-256 — 256-bit hash, widely used and secure
• SHA-512 — 512-bit hash, strongest option
