SHA-512/224 is a truncated version of SHA-512, producing a 224-bit (28-byte) hash value rendered as a 56-character hexadecimal number. It uses the SHA-512 algorithm with different initial values.
SHA-512/224 is a variant of SHA-512 that produces a 224-bit digest. It provides the same security as SHA-224 but runs faster on 64-bit platforms.
