SHA3-224 File Hash
Calculate a SHA3-224 hash from a local file or file URL. Local files are processed in your browser. Read more
What is SHA3-224?
SHA3-224 is the 224-bit SHA-3 hash defined in NIST FIPS 202. This tool hashes a file’s raw bytes. It is not interchangeable with SHA-224 or Keccak-224 File Hash, despite the shared output length.
How to use this file hash calculator
Choose a local file or enter a file URL, then select Hex, Base64, or another output encoding. Local files are processed in the browser without upload. Remote URLs must allow cross-origin access through CORS.
Result example
A file containing exactly the three bytes abc produces e642824c3f8cf24ad09234ee7d3c766fc9a3a5168d0c94ad73b46fdf in Hex. The filename and filesystem metadata are not included.
Important limitations
An unkeyed SHA3-224 digest can detect changed bytes but cannot prove who supplied a file. Obtain the expected digest independently through a trusted channel.
Frequently asked questions
Why does my result differ from another tool?
Confirm both tools use SHA3-224 and read identical raw bytes. SHA-224 and Keccak-224 produce different results.
Can I use the result to verify a download?
Yes, if a trusted publisher provides a SHA3-224 digest. For text with a chosen character encoding, use the SHA3-224 calculator.
