What is Hashing?
Hashing is a one-way cryptographic function that converts data of any size into a fixed-size string of characters. It's designed to be deterministic (same input always produces the same output) and irreversible (you cannot recover the original data from the hash).
MD5: 128-bit hash, fast but not secure for cryptographic purposes.
SHA-1: 160-bit hash, deprecated for security-sensitive applications.
SHA-256: 256-bit hash, widely used and secure.
SHA-384: 384-bit hash, truncated version of SHA-512.
SHA-512: 512-bit hash, strongest in SHA-2 family.
Deterministic: Same input always yields same output
Fixed Size: Output length is constant regardless of input
Irreversible: Cannot recover original data from hash
Collision Resistant: Hard to find two inputs with same hash
Avalanche Effect: Small input change creates big hash change
