Keccak-384 File Hash
Calculate a Keccak-384 hash from a local file or file URL. Local files are processed in your browser. Read more
What is Keccak-384?
Keccak-384 hashes raw file bytes to a 384-bit result using the original Keccak submission’s suffix. It differs from standardized SHA3-384 File Hash. Refer to the Keccak specifications summary when matching an implementation or protocol.
How to use this file hash calculator
Choose a local file or URL and select the output format. Local files are processed without upload. A file URL must allow cross-origin browser requests.
Result example
A file containing the three bytes abc produces f7df1165f033337be098e7d288ad6a2f74409d7a60b49c36642218de161b1f99f8c681e4afaf31a34db29fb763e3c28e in Hex. Filename and metadata do not affect it.
Important limitations
An unkeyed digest detects byte differences but does not authenticate the source. Only compare with a Keccak-384 value obtained independently through a trusted channel.
Frequently asked questions
Why does my result differ from another tool?
Confirm Keccak-384 rather than SHA3-384, then compare the raw bytes processed by each tool.
Can I use the result to verify a download?
Yes, when the expected value explicitly identifies Keccak-384 and is trusted. For encoded text, use the Keccak-384 calculator.
