SHA512/224
Calculate a SHA-512/224 hash or HMAC from text using UTF-8, Hex, Base64, and other input encodings. Read more
What is SHA512/224?
SHA-512/224 is a 224-bit SHA-2 hash standardized in NIST FIPS 180-4. It uses SHA-512’s 64-bit word and 1024-bit block processing with a distinct initialization value, then takes the leftmost 224 bits of that function’s final state. It is not a truncated ordinary SHA-512 digest and does not match SHA-224.
How to use this hash calculator
Enter the text, choose the input encoding, and select the output format. Leave HMAC disabled for a regular SHA-512/224 digest. Enable it only for HMAC-SHA-512/224 and enter the secret key using its actual encoding.
Result example
SHA-512/224 of UTF-8 abc is 4634270f707b6a54daae7530460842e20e37ed265ceee9a43e8924aa in Hex.
Important limitations
Neither SHA-512/224 nor HMAC encrypts the message. An unkeyed digest does not authenticate its source; HMAC depends on a strong secret key. Do not use a fast SHA-2 function directly for password storage.
Frequently asked questions
Why does my result differ from another tool?
Check the exact algorithm name, message bytes, encoding, line endings, and HMAC mode. SHA-512/224 and SHA-224 have equal-length but different outputs.
Can I use the result to verify data?
Yes, when the expected SHA-512/224 value comes from a trusted source. For files, use SHA-512/224 File Hash.
