Does this tool send my text to a server?

No. All hashing is performed by your browser's built-in WebCrypto API (window.crypto.subtle). Your input never leaves your device.

What is the output length of SHA-512?

SHA-512 always produces a 512-bit (64-byte) digest, displayed as 128 hexadecimal characters.

Can I hash passwords with this tool?

SHA-512 alone is not suitable for password storage in production — use a slow hash like bcrypt or Argon2. However, this tool is useful for educational or verification purposes.

What is the difference between uppercase and lowercase output?

Both represent the same hash value. Hexadecimal digits A–F can be written in upper or lower case; the choice is purely stylistic. Many systems use lowercase by convention.

How does SHA-512 differ from SHA-256?

SHA-512 produces a 128-character hex digest (512 bits), while SHA-256 produces a 64-character hex digest (256 bits). SHA-512 offers a larger security margin and can be faster than SHA-256 on 64-bit hardware.
