SHA-256 hash
Hash text locally (hex/Base64). Copy output or share a link.
Format

This tool runs only in your browser. It does not upload your input anywhere.

Security note: SHA-256 is not suitable for password storage. Use a dedicated password hashing algorithm (e.g. bcrypt/Argon2) for that.

Tip: “Share link” encodes your input and options in the URL hash (so treat shared links as sensitive).
