SHA-512 is the SHA-2 family’s 512-bit variant, producing a 128-character hexadecimal digest that is larger and, on 64-bit processors, faster than SHA-256. It is used in specific niches: DNSSEC zone signing, some TLS cipher suites, and protocols that mandate a 512-bit output size. For most applications, SHA-256 is the right default — it is the one embedded in every browser, every operating system, and every standard. The SHA-512 tool exists alongside the SHA-256 and SHA-1 tools as a complete set of SHA-2 hash functions, all computing locally in your browser.

How to use

  1. Enter your text

    Type or paste the text. The 128-character SHA-512 digest updates in real-time. Drop a file to hash locally.

  2. Copy the result

    Copy the 128-character hex string. The larger output size (512 bits) is useful where protocol mandates it.

  3. Choose between SHA-512 and SHA-256

    SHA-256 is the standard for most applications. Use SHA-512 only when a protocol or specification requires a 512-bit digest.

Frequently asked

When should I use SHA-512 instead of SHA-256?

SHA-512 is faster than SHA-256 on 64-bit processors because it operates on 64-bit words natively. However, SHA-256 is the de facto standard — use SHA-512 only when a protocol, specification, or hardware constraint specifically requires a 512-bit output size.

Is SHA-512 more secure than SHA-256?

SHA-512 has a larger output size (512 bits vs 256 bits), which provides a larger security margin against future attacks, but both hash functions have the same cryptanalytic resistance as of 2026. The practical difference is the output length, not the security margin.

Can I truncate a SHA-512 hash to 256 bits?

Yes — SHA-512/256 is a standardised variant that computes SHA-512 and truncates the output to 256 bits. This tool computes the full 512-bit digest. Truncate externally if needed.

Limitations

  • Not for password hashingSHA-512 is a fast hash. Use bcrypt, scrypt, or Argon2id for password storage.

Platform notes

macOS
Terminal: `shasum -a 512 filename`. The browser tool is for one-off hashing.
Web
Runs client-side. Files are hashed locally.
