Keccak-384
Calculate a Keccak-384 hash from text using UTF-8, Hex, Base64, and other input encodings. Read more
What is Keccak-384?
Keccak-384 is the 384-bit hash from the original Keccak SHA-3 competition submission. Its domain-separation suffix differs from standardized SHA3-384, so their digests do not match. The Keccak specifications summary describes the sponge family and its parameters.
How to use this hash calculator
Enter the text, choose its byte encoding, and select Hex, Base64, or another result format. Use this variant only when the protocol or test vector explicitly requests Keccak-384.
Result example
Keccak-384 of UTF-8 abc is f7df1165f033337be098e7d288ad6a2f74409d7a60b49c36642218de161b1f99f8c681e4afaf31a34db29fb763e3c28e in Hex.
Important limitations
Keccak-384 is not encryption, authentication, or password hashing. A longer digest does not resolve an algorithm mismatch: always distinguish original Keccak from FIPS-standardized SHA-3.
Frequently asked questions
Why does my result differ from another tool?
Confirm the expected family is Keccak rather than SHA3, then check the exact bytes, character encoding, and line endings.
Can I use the result to verify data?
Yes, if the expected Keccak-384 digest comes from a trusted source. For raw files, use Keccak-384 File Hash.
