Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes. All computation happens locally in your browser using the Web Crypto API.
About hash functions
MD5 — 128-bit, fast but cryptographically broken. Still useful for checksums and non-security use cases.
SHA-1 — 160-bit, deprecated for security. Avoid for new systems requiring collision resistance.
SHA-256 — 256-bit, part of the SHA-2 family. Widely used for digital signatures, blockchain, and certificate validation.
SHA-512 — 512-bit, SHA-2 family. Used where longer hash output is needed.
All hashing is performed locally using the browser's built-in Web Crypto API (crypto.subtle.digest). Your data is never sent to any server.
