What is SHA224 Hash Generator?

SHA-224 is a SHA-2 family hash function with a 224-bit output. It uses SHA-256-style compression with different initial values and a shorter final digest.

Use SHA-224 when a protocol, fixture, or API explicitly expects it. For general modern use, SHA-256 is usually more common and better supported.

How to Use SHA224 Hash Generator

1

Type or paste the text you want to hash

2

Review the generated SHA-224 output

3

Toggle uppercase if your target system expects capital hex

4

Copy the digest for comparison or fixtures

Common Use Cases

  • Generating SHA-224 fixtures for compatibility tests.
  • Matching APIs that require 224-bit SHA-2 output.
  • Comparing SHA-224 with SHA-256 from the same source text.
  • Documenting expected SHA-224 digests in test suites.

Example Input and Output

Generate the standard SHA-224 digest for a short string.

Input text
abc
SHA-224 hash

How This Tool Works

The tool encodes input as UTF-8 bytes, applies SHA-224 padding and compression locally, and formats the 224-bit digest as hexadecimal.

Variant

FIPS 180 SHA-224 over UTF-8 input bytes.

Security note

SHA-224 is part of SHA-2, but SHA-256 is more widely supported for modern integrity checks.

Frequently Asked Questions

How long is a SHA-224 hash?
SHA-224 outputs 224 bits, displayed as 56 hexadecimal characters.
Is SHA-224 the same as truncated SHA-256?
No. SHA-224 uses different initial hash values and then outputs seven 32-bit words.
Should I use SHA-224 or SHA-256?
Use SHA-256 unless you specifically need SHA-224 for compatibility.
Is input uploaded?
No. Hashing runs locally in your browser.
