SHA3-224
Calculate a SHA3-224 hash from text using UTF-8, Hex, Base64, and other input encodings. Read more
What is SHA3-224?
SHA3-224 is a fixed-output cryptographic hash standardized in NIST FIPS 202. It uses the Keccak sponge construction and always returns 224 bits. It is a different algorithm from SHA-224 in the SHA-2 family and from the original Keccak-224, so their digests do not match.
How to use this hash calculator
Enter the text, choose how it should be converted to bytes, and select the output encoding. Hex output contains 56 characters because each hexadecimal character represents four of the 224 result bits.
Result example
SHA3-224 of UTF-8 abc is e642824c3f8cf24ad09234ee7d3c766fc9a3a5168d0c94ad73b46fdf in Hex.
Important limitations
SHA3-224 is not encryption and an unkeyed digest does not authenticate its input. Do not use a fast general-purpose hash directly for password storage; use a dedicated password-hashing function.
Frequently asked questions
Why does my result differ from another tool?
Check the input bytes, encoding, line endings, and exact algorithm name. SHA3-224, SHA-224, and Keccak-224 are separate functions.
Can I use the result to verify data?
Yes, if the expected SHA3-224 value comes from a trusted source. For raw file bytes, use SHA3-224 File Hash.
