Generate SHA-512 and SHA-384 hashes online for free using the Web Crypto API. Hash text instantly in your browser. No uploads, no signup required.

When SHA-256 isn't enough margin — or a spec simply demands the bigger digest — SHA-512 is the SHA-2 family's heavyweight, producing a 128-character hexadecimal fingerprint of any input. Our free SHA-512 Hash Generator computes it instantly in your browser, along with its truncated sibling SHA-384, using the platform's native Web Crypto implementation.
Because hashing runs through crypto.subtle.digest on your own device, the output is standards-exact, the computation is effectively instant even for large inputs, and — critically — whatever you hash never crosses the network. That makes the tool safe for hashing secrets, API payload signatures, and pre-release content.
Common uses include verifying file and download checksums published as SHA-512, generating test vectors for backend code, and creating content fingerprints for deduplication. For other algorithms, see our SHA-256 Hash Generator and legacy MD5 Hash Generator, or build keyed signatures with the HMAC Generator.
