SHA3-384 is a member of the SHA-3 family standardised in FIPS 202. It uses the Keccak[768] sponge with an 832-bit rate and produces a 384-bit output.
SHA3-384 is suitable when a 256-bit digest is not long enough for a given security requirement, but a full 512-bit output is not necessary. It provides a 192-bit security level against collision attacks.
How to Use SHA3-384 Hash Generator
Type or paste the text you want to hash
Review the generated SHA3-384 output
Toggle uppercase if your target system expects capital hex
Copy the digest for comparison or storage
Common Use Cases
- Generating SHA3-384 fixtures for high-security test suites.
- Hashing data where 256-bit output is insufficient.
- Verifying Keccak-based 384-bit implementations.
- Comparing SHA3-384 with SHA-384 for the same input.
Example Input and Output
Generate the FIPS 202 SHA3-384 digest for a short string.

The tool encodes input as UTF-8 bytes, applies Keccak-f[1600] with SHA3-384 rate and SHA3 multi-rate padding locally, and formats the 384-bit digest as hexadecimal.

Frequently Asked Questions
How long is a SHA3-384 hash?
SHA3-384 outputs 384 bits, displayed as 96 hexadecimal characters.
What security level does SHA3-384 provide?
SHA3-384 provides approximately 192-bit collision resistance and 384-bit preimage resistance.
Is SHA3-384 the same as SHA-384?
No. Both produce 384-bit outputs, but they use different algorithms and produce different digests.
Is input uploaded?
No. Hashing runs entirely in your browser.
