What is a Hash?

A hash function takes input data and produces a fixed-size string of characters. Hashes are one-way: you can generate a hash from data, but cannot reverse it. Common uses include password storage, data integrity verification, digital signatures, and file checksums.

Hash Algorithms

MD5: 128-bit hash. Fast but not collision-resistant — avoid for security, fine for checksums.
SHA-1: 160-bit hash. Deprecated for security but still used in legacy systems.
SHA-256: 256-bit hash from the SHA-2 family. Widely used in security, blockchain, and certificates.
SHA-512: 512-bit hash. Maximum security from the SHA-2 family.
