{ } How to use

Paste or type your text.
Select Process to get the SHA-512 digest as hexadecimal.

{ } How it works

SHA-512 Hash works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

Text input — paste or type your input in the left panel (use Sample for an example)

Output

TXT text — copy or download it from the Output panel.

{ } Common uses

Produce a digest where a longer output is specified or preferred.
Match a SHA-512 checksum published alongside a download.
Fingerprint a large body of text compactly.

{ } Limitations

The text is hashed as UTF-8 bytes, so a different encoding or a stray trailing newline produces an entirely different digest.
Hashing is one-way and unsalted. It is not encryption, and it is not a password hash: identical inputs always give identical digests, which is exactly what makes a bare digest unsuitable for storing passwords.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Is SHA-512 better than SHA-256?

Not meaningfully, for security. Both are unbroken; SHA-512 gives a longer digest and can be faster on 64-bit hardware. Match whatever the thing you are checking against uses.
