Hash Generator

Calculate MD5 / SHA-1 / SHA-256 / SHA-512 hashes from text

Hash Algorithm Overview

A hash function converts any-length input into a fixed-length output (hash value). The same input always produces the same output, and any tiny change results in a completely different hash.

Algorithm Security Comparison

MD5: 128-bit, fast, collisions found — use only for non-security checksums
SHA-1: 160-bit, compromised — not recommended for security
SHA-256: 256-bit, currently secure — recommended
SHA-512: 512-bit, highest security level
