What is SHA-224 Hash Generator?

SHA-224 belongs to the SHA-2 family standardised in FIPS 180-4. It works like SHA-256 but starts from different initial values and cuts the final result to 224 bits, so its digest is 56 hex characters long. It was designed to match the 112-bit security level of two-key Triple DES.

The tool converts your text to UTF-8 bytes (or reads hex bytes), hashes them with a WebAssembly implementation and displays the digest in hex or Base64, plus the input size. The SHA-224 of "abc" is 23097d22 3405d822 8642a477 bda255b3 2aadbce4 bda0b3f7 e36c9da7.

How does it work?

  1. Type or paste your text. The digest updates automatically.
  2. Choose UTF-8 text or hex bytes as the input type.
  3. Pick hex or Base64 output and upper or lower case letters.
  4. Copy the 56-character digest, or compare it with the value you were given.

Common use cases

  • Reproducing a SHA-224 test vector from FIPS 180-4 or a library test suite.
  • Checking a fingerprint published by a system that still uses SHA-224, such as some embedded and smart-card stacks.
  • Comparing SHA-224 with SHA-256 to see that the same input gives a related but different digest.
  • Generating a shorter digest when a field is limited to 56 hex characters.

Limitations

SHA-224 is not a password hash: it is fast by design. It offers less collision resistance (112 bits) than SHA-256, so prefer SHA-256 or stronger for new designs.

Frequently asked questions

Is SHA-224 just SHA-256 cut to 224 bits?

Not exactly. Truncating a SHA-256 digest would give a different value. SHA-224 uses its own initial hash values, and only then drops the last 32 bits of the final state.

Why does my SHA-224 differ from another tool?

Check for a trailing newline, line-ending differences or a non-UTF-8 encoding. The byte length shown in the result helps you compare with your source.

How many characters does a SHA-224 digest have?

56 hexadecimal characters (28 bytes), or 40 characters in Base64 including two padding signs.
