What is SHA-512?

SHA-512 is a SHA-2 algorithm that outputs a 512-bit (128 hex character) hash. It offers a larger digest than SHA-256 and performs well on 64-bit systems. It's used where the strongest standard hash is desired — integrity verification, signatures, and key derivation building blocks.

Frequently Asked Questions

Is SHA-512 stronger than SHA-256?

It produces a larger digest and can be faster on 64-bit hardware. Both are secure; SHA-256 is more common, SHA-512 offers a bigger hash.

Is the hash reversible?

No — like all cryptographic hashes, SHA-512 is one-way. The original text can't be recovered from the digest.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
