Hash

SHA-512 Hash Generator

Get the 128-character SHA-512 digest of any text as you type — computed locally via Web Crypto.

Hashing runs locally via your browser's Web Crypto API. Nothing is uploaded, logged, or stored.

How to use

  1. Type or paste text into the input panel.
  2. The 128-character hexadecimal digest updates live as you type.
  3. Toggle uppercase output if needed, then copy the hash.

SHA-512 vs SHA-256?

SHA-512 produces a 512-bit digest — double the output of SHA-256 — and is often faster on 64-bit hardware because its internals use 64-bit arithmetic. It is a solid choice where you want maximum collision margin or must comply with policies that mandate a 512-bit digest. Like SHA-256, it is computed here by the browser's native Web Crypto implementation.

Compare with SHA-256 side by side, or use the HMAC Generator when the digest must be keyed with a secret.

Examples

High-assurance integrity

Digest firmware notes, manifests, or audit trails where a longer hash is required by policy.

Key derivation inputs

Stretch secrets through SHA-512 as a first step before feeding a proper KDF.

Frequently Asked Questions

Is my text uploaded anywhere?+
No. Hashing happens inside your browser's Web Crypto API.
Is SHA-512 more secure than SHA-256?+
It offers a larger security margin on paper, but both are far beyond practical attack today. Choose SHA-512 when policy or interoperability demands it.
Why is the output 128 characters?+
512 bits equals 64 bytes, which renders as 128 hexadecimal characters.
Can I hash non-ASCII text?+
Yes — input is encoded as UTF-8 bytes before hashing, matching standard tooling.
