Hash Generator
Generate SHA-256, SHA-1, and SHA-384 hashes from text using the Web Crypto API.
100% client-side — your data never leaves this device.
Hashes update as you type. Computed with the Web Crypto API — never sent to a server.

Note: Hashing is one-way. Do not use plain hashes alone for password storage — use a dedicated password hashing scheme (bcrypt, Argon2, etc.).
Cryptographic hashes
Generate digests with the browser Web Crypto API. Useful for checksums and integrity checks. Not a substitute for proper password hashing (use bcrypt/Argon2 on the server for passwords).
