Input
What is SHA-224?
SHA-224 is a cryptographic hash function that produces a fixed-size hash value from variable-length input data. It's part of the SHA-2 family designed by the NSA and published in 2001. SHA-224 produces a 224-bit hash value and is widely used in security applications and protocols.
How to Use SHA-224
1. Enter or paste your text into the input field. 2. The SHA-224 hash is calculated instantly as you type. 3. Click "Copy" to copy the hash value to your clipboard. 4. Use the "Clear" button to reset and start over.
When to Use SHA-224
Use SHA-224 when you need secure cryptographic hashing for certificates, blockchain applications, password storage, or data integrity verification in production systems.
How SHA-224 Works
SHA-224 uses a Merkle–Damgård construction with multiple rounds of bit operations including rotations, modular additions, and logical functions. Each message block goes through compression functions that mix the input thoroughly.
Common Use Cases
- SSL/TLS certificates
- Blockchain technology
- Digital signatures
- Password hashing
- HMAC authentication
