About Hash Generator
A cryptographic hash function takes an input and produces a fixed-size output (the hash/digest) that uniquely represents the input. Even a tiny change in the input produces a completely different hash — this is known as the avalanche effect.
SHA-256 and SHA-512 are the most widely used algorithms today and are recommended for security applications. SHA-1 is considered cryptographically weak and should only be used for non-security purposes like checksums. This tool uses the browser's native Web Crypto API — no data ever leaves your device.
