SHA-224 is a member of the SHA-2 family (FIPS PUB 180-4). It produces a 224-bit (28-byte) digest encoded as 56 lowercase hex characters. It is structurally identical to SHA-256 but uses different initialization constants and truncates the output, making it slightly smaller while retaining the same algorithmic security properties.

Is my input sent to a server?

No. All hashing runs entirely in your browser using the WebCrypto SubtleCrypto API. Your text never leaves your device, making this tool safe for sensitive data.

Batch Mode splits your input by line and hashes each line independently. The output lists each original line alongside its SHA-224 hash, which is useful for processing many strings at once.

Why is the hash always 56 characters?

SHA-224 always outputs a fixed 224-bit digest regardless of input length. When expressed as lowercase hexadecimal (2 characters per byte), this is always exactly 56 characters.

How does SHA-224 differ from SHA-256?

SHA-224 and SHA-256 share the same compression function but differ in initial hash values and output length. SHA-224 outputs 224 bits (56 hex chars) versus 256 bits (64 hex chars) for SHA-256. SHA-224 is commonly used in X.509 certificate signatures where the smaller output is preferred.

Is SHA-224 secure for passwords?

SHA-224 alone is not recommended for password hashing because it is a fast algorithm. For passwords, use a purpose-built slow hash function such as bcrypt, scrypt, or Argon2. SHA-224 is suitable for data integrity checks and digital signatures.

About SHA-224

SHA-224 belongs to the SHA-2 family (FIPS PUB 180-4). It produces a 224-bit (56 hex character) digest using the same compression function as SHA-256 but with different initialization constants and a truncated output. Widely used in X.509 certificates and TLS handshakes.

Summary

Generate SHA-224 hashes from text or multiple lines at once — computed instantly in your browser with no data sent to any server.

How it works

Type or paste your text into the input field.
Switch to Batch Mode to hash multiple lines simultaneously — one hash per line.
The SHA-224 digest is computed live using the browser's built-in WebCrypto API.
Each result is a fixed 56-character lowercase hexadecimal string.
Toggle uppercase output using the provided option.
Copy the result with one click — nothing ever leaves your device.

Use cases

Generate compact 224-bit digests for use in digital certificates and TLS.
Hash multiple strings at once in batch mode for bulk data processing.
Verify text integrity by comparing SHA-224 checksums.
Test server-side SHA-224 implementations against known-good browser output.
Create deterministic identifiers from arbitrary string inputs.
Hash API tokens for safe logging without exposing raw secret values.
Use as a lighter alternative to SHA-256 when a smaller digest suffices.
Quickly confirm two strings differ without directly comparing them.
