About SHA-512 Generator
SHA-512 is SHA-256's larger sibling, producing a 512-bit digest instead of 256. Both belong to the SHA-2 family and both are unbroken; the choice between them is usually driven by a specification rather than by security.
A useful quirk: on 64-bit processors SHA-512 frequently runs faster than SHA-256, because its internal operations work on 64-bit words that map directly onto the hardware. On 32-bit devices the reverse is true.
Everything is computed locally in your browser, including file hashing, so nothing you check is transmitted.
Frequently asked questions
Is SHA-512 more secure than SHA-256?
It has a larger output, but both are considered secure and neither has a practical attack. SHA-256 is the more common default; SHA-512 is chosen where a longer digest is mandated.
Is SHA-512 slower?
On 64-bit hardware it is often slightly faster than SHA-256, because it works on 64-bit words. On 32-bit devices it is slower.
How long is the output?
128 hexadecimal characters, representing 512 bits.
Where is SHA-512 used?
Linux password hashing via crypt, some government and financial standards that specify a minimum digest length, and as the basis of SHA-512/256.
Is it free?
Yes — unlimited use, no sign-up, no watermark and no limit on how many times you run it.
