SHA-224 is a member of the SHA-2 family defined in FIPS PUB 180-4. It produces a 224-bit (28-byte, 56 hex character) digest and is essentially a truncated version of SHA-256 with different initial hash values. It offers a smaller output size while retaining the same structural security properties as SHA-256.

Is my input sent to a server?

No. All hashing is performed locally in your browser using the WebCrypto SubtleCrypto API. Your text never leaves your device.

How does SHA-224 differ from SHA-256?

SHA-224 uses the same algorithm structure as SHA-256 but starts with different initial constants and truncates the final digest from 256 bits to 224 bits. The output is 56 hex characters instead of 64. SHA-224 is slightly smaller and is commonly used in certificate signatures where the shorter digest is an advantage.

SHA-224 is considered cryptographically secure for most use cases as of 2024. No practical collision attacks are known. However, for new designs requiring maximum security margin, SHA-256 or SHA-3 are generally recommended. SHA-224 remains widely used in X.509 certificates and TLS handshakes.

Can I hash binary data or files with this tool?

This tool hashes text encoded as UTF-8. For binary file hashing, you would need a tool that reads file bytes directly. Text input is converted to UTF-8 bytes before hashing, which is the standard behavior.

Why is the output always 56 characters long?

SHA-224 always produces a fixed-size 224-bit output regardless of input length. When encoded as lowercase hexadecimal (where each byte becomes two hex characters), the result is always exactly 56 characters.

About SHA-224

SHA-224 is part of the SHA-2 family (FIPS PUB 180-4). It produces a 224-bit (56 hex characters) digest — a truncated variant of SHA-256 with different initialization constants. Commonly used in X.509 certificates and TLS handshakes where a slightly smaller digest is preferred over SHA-256.

How it works

Type or paste your input text into the text area.
The SHA-224 digest is computed live in your browser using the WebCrypto SubtleCrypto API.
The result is displayed in lowercase hexadecimal (56 characters).
Use the Copy button to copy the hash to your clipboard.
Toggle uppercase output or add a line-break-separated batch with the options provided.
No data leaves your device — all computation happens client-side.

Use cases

Verify file or message integrity by comparing SHA-224 checksums.
Generate compact digests for use in certificate chains and TLS.
Create deterministic identifiers from string data in applications.
Test and debug cryptographic pipelines that rely on SHA-224 output.
Confirm that two pieces of text are identical without comparing them directly.
Quickly hash API tokens or secrets for logging without exposing the raw value.
Validate SHA-224 output from server-side code against a known-good value.
Use as a lighter alternative to SHA-256 when a 224-bit digest suffices.
