String to SHA-512

Generate the SHA-512 hash of any text instantly. Free online SHA-512 tool, plus when to prefer it over SHA-256.

Open the hash generator →All free tools

Paste text and get its SHA-512 digest — a 128-character hex fingerprint from the SHA-2 family. It is secure like SHA-256 and can be faster on 64-bit hardware.

When to use SHA-512

Choose SHA-512 when you want a longer digest or measured better throughput on 64-bit servers for large inputs. It has no practical collision attack, so it is as safe as SHA-256 for integrity and signing.

Not for passwords

Like all fast hashes, SHA-512 is the wrong tool for password storage — use a slow salted KDF (bcrypt, scrypt, Argon2) there. SHA-512 is for integrity and content addressing, not credentials.
