SHA-512 Hash Generator
Free SHA-512 hash generator. Create SHA-512 hashes from any text instantly.
How SHA-512 Hash Generator Works
Applies SHA-512 to produce a 512-bit (128 hex character) digest. SHA-512 is faster than SHA-256 on 64-bit systems due to operating on 64-bit words, and provides a larger security margin.

Frequently Asked Questions
What is SHA-512?
SHA-512 produces a 512-bit (128 hex character) hash — twice the output size of SHA-256. Part of the SHA-2 family. Despite its larger output, SHA-512 is often faster than SHA-256 on 64-bit hardware because it operates on 64-bit words rather than 32-bit words.
SHA-256 vs SHA-512 — which should I use?
SHA-256 for most applications — it's the standard and widely compatible. SHA-512 when you need a larger security margin (very long-term data integrity) or when you're on 64-bit hardware and performance matters. Both are considered equally secure for current threats.
What is SHA-512 used for?
TLS certificate fingerprinting, high-security API signing, Unix password storage (SHA-512 crypt is the default on many Linux systems — though bcrypt is better for new applications), and data integrity for large files where the extra security margin is valued.
Is my data stored?
No.
Can I use this on mobile?
Yes.
