Generate secure SHA-224 hashes from plain-text input. This tool is useful for data integrity verification, password storage, and cryptographic operations.
Supported Tools:
Generate and verify SHA-224 hashes online. SHA-224 is the 224-bit member of the SHA-2 family, produced by truncating SHA-256 with a different initial state.
SHA-224 is a cryptographic hash function from the SHA-2 family standardized in FIPS 180-4. It outputs a 224-bit (28-byte) digest, written as 56 hexadecimal characters. Internally it runs the same compression function as SHA-256 but starts from a different set of initial hash values and truncates the final result to 224 bits. It is most often seen where a slightly shorter digest than SHA-256 is wanted while keeping SHA-2 level security, such as certain certificate and DSA parameter sizing scenarios.
Input:
abc
Output:

Is SHA-224 just a shorter SHA-256?
Almost. It uses the same SHA-256 block algorithm but with a distinct initial hash value and truncates the output to 224 bits, so the digests are not a simple prefix of a SHA-256 hash.
Is SHA-224 secure?
Yes, SHA-224 has no known practical collision or preimage attacks and is considered secure for integrity use. For password storage, use a dedicated KDF like bcrypt or Argon2 instead.
How long is a SHA-224 hash?
224 bits, shown as 56 hexadecimal characters.
