What is SHA-512/256 Hash Generator

Last reviewed: April 18, 2026

SHA-512 is a SHA-2 family hash function that outputs 512 bits, often used when extra hash strength or internal 64-bit operations are preferred.

SHA-512/256 Hash Generator produces a 64-character hexadecimal digest using SHA-512 internals and the FIPS 180-4 SHA-512/t output length of 256 bits.

It is popular in cryptocurrencies and certain enterprise systems because it offers SHA-512 throughput on 64-bit hardware while matching the 256-bit slot size used by SHA-256.

Why use it

Drop in a 256-bit SHA-2 digest that is faster than SHA-256 on 64-bit CPUs.
Align with Bitcoin Cash, NEAR Protocol, and other SHA-512/256 consumers.
Fulfill spec requirements that call out SHA-512/256 specifically.
Generate algorithm-diverse 256-bit fingerprints beside SHA-256.
Validate reference vectors during library testing.

Features

64-character SHA-512/256 hex output
FIPS 180-4 compliant truncation
Faster than SHA-256 on 64-bit hardware
Runs entirely in the browser
Deterministic output for UTF-8 input

How to use SHA-512/256 Hash Generator

Paste your text. Drop the string you want to hash into the input panel.
Read the digest. The tool shows the 64-character SHA-512/256 hex digest.
Copy the hash. Use the copy button to move the hash into your workflow.

Common errors

Confusing SHA-512/256 with SHA-256

The two share an output length but use different internals and initialization vectors.

Fix: Pick the exact variant your protocol or spec requires.

Manually truncating SHA-512

Cutting a SHA-512 hex string to 64 characters is not the same as SHA-512/256.

Fix: Use a dedicated SHA-512/256 implementation like this tool.

Skipping canonicalization

Different whitespace or line endings produce different digests and break hash comparisons.

Fix: Canonicalize input before hashing when you need cross-system parity.

FAQ

Where is SHA-512/256 used?

In some cryptocurrency projects and enterprise systems that want a 256-bit SHA-2 output with SHA-512 performance.

Is it faster than SHA-256?

Often yes on 64-bit CPUs, because SHA-512 operates on 64-bit words natively.

Is it secure?

Yes. It offers 128-bit collision resistance.

Does OpenSSL support it?

Yes: `openssl dgst -sha512-256` matches the output of this tool.

Is hashing performed in-browser?

Yes. Your input stays on your device.

Can I use SHA-512/256 for passwords?

No. Use bcrypt, argon2, or scrypt for password storage.
