Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text — private and free.

100% client-side — your data never leaves this device.

Hashes update as you type. SHA-* uses Web Crypto; MD5 is computed in pure JS. Nothing is sent to a server.

Hashes

MD5(legacy)

SHA-1

SHA-256

SHA-384

SHA-512

MD5 and SHA-1 are weak for security. Prefer SHA-256+ for integrity checks. Never store passwords with plain hashes — use bcrypt/Argon2.

Cryptographic hashes

Generate digests with the browser Web Crypto API (SHA family) plus a local MD5 implementation for legacy checksums. Useful for integrity checks — not a substitute for proper password hashing (use bcrypt/Argon2 on the server).
