Online SHA-224 Hash Generator
SHA-224 is a member of the SHA-2 family that produces a 224-bit hash value (56 hexadecimal characters). It is a truncated variant of SHA-256 using different initial values.

About SHA-224
SHA-224 is one of the hash functions in the SHA-2 family, designed by the National Security Agency (NSA) and published by NIST in 2004 (FIPS 180-2). The "224" indicates the output length: 224 bits, shown as 56 hexadecimal characters, regardless of input length.
How it works: SHA-224 uses exactly the same core algorithm as SHA-256 — processing data in 512-bit blocks through 64 compression rounds. The only differences are a distinct set of initial hash values and that the final result is truncated to 224 bits. Because of this, SHA-224 inherits the security strength of SHA-256, just with a shorter output.
SHA-224 is useful when you need security comparable to SHA-256 but a more compact digest — for example in certain protocols or certificates that constrain hash length. For most general purposes SHA-256 is more popular, but SHA-224 remains secure and a standard part of the SHA-2 family.
FAQ
What is the difference between SHA-224 and SHA-256?
Both use the same core algorithm. SHA-224 only differs in its initial hash values and produces a 224-bit output (56 hex), while SHA-256 produces 256 bits (64 hex). SHA-224 is more compact but offers comparable security for most needs.
Is SHA-224 secure?
Yes. As part of the SHA-2 family, SHA-224 is currently considered secure with no known practical collision attacks, unlike MD5 and SHA-1 which are obsolete for security.
Is my data sent to a server?
No. The SHA-224 hash is computed entirely in your browser using JavaScript. The text you enter never leaves your device.
How long is a SHA-224 hash?
A SHA-224 hash is always 224 bits long, displayed as 56 hexadecimal characters, regardless of the input length.
