About SHA-224

SHA-224 is a cryptographic hash function from the SHA-2 family. It produces a 224-bit (56-character hexadecimal) hash value. SHA-224 is similar to SHA-256 but with a reduced digest size, achieved by truncating the internal state of the algorithm before the final step.

While SHA-224 is part of the SHA-2 family, it is less commonly used than SHA-256 or SHA-512. It is primarily used in applications where a shorter hash value is desired but the security of SHA-2 is still required. SHA-224 is considered secure against all known attacks as of current research.
