SHA-512/256 Hash Generator

Generate the SHA-512/256 hash of any text or file. The 256-bit digest is computed locally in your browser and updates on every keystroke. Switch to File mode to fingerprint downloads and verify checksums without uploading anything.

About SHA-512/256

SHA-512/256 is a member of the SHA-2 family, published by NIST in FIPS 180-4. SHA-512/256 is defined in FIPS 180-4 as SHA-512 with a distinct initialization vector, truncated to 256 bits. The same input always yields the same digest, and a one-character change produces a completely different value.

Features

Hex, uppercase HEX, or Base64 output
Hash each line for bulk processing of lists
Compare with a known hash to verify integrity instantly

Security

SHA-2 is the current workhorse for cryptographic hashing: TLS certificates, software signatures, blockchain systems, and file integrity all rely on it. For password storage, use a slow algorithm such as bcrypt (see the WordPress Password Hash Generator); for keyed message authentication, use the HMAC Generator. To see the whole family side by side, try the SHA2 Hash Generator, and for the newer sponge design see SHA3-256.

Frequently Asked Questions

How long is a SHA-512/256 hash?

SHA-512/256 produces 256 bits, shown here as 64 hexadecimal characters. You can also switch the output to uppercase or Base64.

Is SHA-512/256 secure?

Yes. The SHA-2 family has no known practical collision or preimage attacks and is recommended by NIST for digital signatures, certificates, and integrity checks.

Why use SHA-512/256 instead of SHA-256?

SHA-512/256 gives the same 256-bit output but is built on the 64-bit SHA-512 engine, so it is often faster on modern 64-bit CPUs and is naturally resistant to length-extension attacks.

How do I verify a file's SHA-512/256 checksum?

Switch to File mode, drop the file in, and paste the published checksum into the compare box. A green message confirms the file matches. The file never leaves your browser.
