What is SHA3-384 Hash Generator

Last reviewed: April 18, 2026

SHA-3 is the latest member of the Secure Hash Algorithm family, based on the Keccak sponge construction and designed as a backup to SHA-2.

SHA3-384 Hash Generator takes a text input and outputs a 96-character hexadecimal SHA3-384 digest derived from the Keccak sponge construction as standardized by NIST FIPS 202.

The extra length is useful for long-lived artifacts such as certificate pins, release manifests, and archive integrity records where you want a safety margin beyond SHA-256.

Why use it

Generate 384-bit fingerprints for release artifacts and long-term archives.
Provide FIPS 202 compliance alongside existing SHA-2 pipelines.
Produce certificate-pin sized hashes for defense-in-depth verification.
Match SHA3-384 reference vectors during library testing.
Avoid MD5, SHA-1, and RIPEMD for modern integrity workflows.

Features

96-character hex output from any UTF-8 input
FIPS 202 compliant SHA3-384 implementation
Matches OpenSSL `dgst -sha3-384` output
Client-side hashing with no server round trip
Ideal for long-term artifact fingerprints

How to use SHA3-384 Hash Generator

Paste the text. Drop your payload into the input field.
Read the 96-char digest. SHA3-384 is computed on the fly and shown in the output panel.
Copy the hash. Use the copy button to keep the full digest intact.

SHA3-384 hex digest

Common errors

Truncating the hex output

Copy-pasting through narrow terminals can cut the 96-character digest.

Fix: Use the copy button so the full hex string is preserved.

Assuming SHA3-384 is interchangeable with SHA-384

SHA-384 (SHA-2 family) and SHA3-384 share a length but use different algorithms and produce different output.

Fix: Pick the tool and algorithm label that matches the spec you are implementing.

Using SHA3-384 for password storage

Single-pass hashes do not include work factor and are not suitable for storing credentials.

Fix: Use bcrypt, argon2, or scrypt for passwords instead.

FAQ

How long is a SHA3-384 digest?

384 bits, shown as 96 hexadecimal characters.

Is SHA3-384 stronger than SHA3-256?

It offers a larger security margin against collisions, which matters for long-lived fingerprints.

Is SHA3-384 in OpenSSL?

Yes. `openssl dgst -sha3-384` returns the same digest as this tool for identical input.

Do I need the extra length over SHA3-256?

Usually no, but use SHA3-384 when you need certificate-pin sized output or must meet specific compliance.

Can this tool hash files?

It hashes pasted text. For file hashing, use a dedicated file-checksum tool or the OpenSSL CLI.

Does the hashing happen in the browser?

Yes. Your input is never sent to a server.
