SHA3-384 File Hash
Calculate a SHA3-384 hash from a local file or file URL. Local files are processed in your browser. Read more
What is SHA3-384?
SHA3-384 is the fixed 384-bit SHA-3 hash defined in NIST FIPS 202. This calculator hashes raw file bytes. It does not produce the same result as SHA-384 or the original Keccak-384 File Hash.
How to use this file hash calculator
Choose a local file or enter a URL, then select an output encoding. Local files are processed without upload. Browser security requires a remote URL to allow CORS access.
Result example
A file containing exactly the bytes abc produces ec01498288516fc926459f58e2c6ad8df9b473cb0fc08c2596da7cf0e49be4b298d88cea927ac7f539f1edf228376d25 in Hex. The filename is not hashed.
Important limitations
An unkeyed SHA3-384 hash can show that bytes differ, but it cannot prove who published the file. Compare against an expected value obtained independently from a trusted source.
Frequently asked questions
Why does my result differ from another tool?
Confirm both tools use SHA3-384 and process the same raw bytes. SHA-384 and Keccak-384 are different algorithms.
Can I use the result to verify a download?
Yes, when a trusted publisher provides a SHA3-384 value. For text with an explicit encoding, use the SHA3-384 calculator.
