SHA-224 Hash Generator
What is SHA-224 Hash?
SHA-224 is a cryptographic hash function that produces a 224-bit (28-byte) hash value. It's part of the SHA-2 family of hash functions designed by the NSA and published in 2001. SHA-224 is essentially a truncated version of SHA-256, using different initial hash values.
How Does This SHA-224 Generator Work?
Our free online SHA-224 generator tool allows you to quickly create SHA-224 hashes from any text input. Simply paste or type your text into the input box, click "Generate SHA-224 Hash," and you'll instantly get the 56-character hexadecimal hash value.
Common Uses of SHA-224
- Data Integrity: Verify that files or messages haven't been altered
- Password Storage: Safely store password hashes (though more secure options exist)
- Digital Signatures: Used in some cryptographic protocols
- Blockchain Technology: Some cryptocurrencies use SHA-224 for various purposes
SHA-224 vs Other Hash Functions
SHA-224 provides better security than SHA-1 (which is now considered broken) but is less commonly used than SHA-256 or SHA-512. The main advantage is its shorter output size while maintaining good security properties.
Is SHA-224 Secure?
As of 2023, SHA-224 remains secure against known cryptographic attacks. However, for new applications, SHA-256 or SHA-3 are generally recommended as they provide stronger security margins.
Technical Details of SHA-224
SHA-224 uses:
- Block size of 512 bits (64 bytes)
- Word size of 32 bits
- 64 rounds of processing
- Produces a 224-bit digest (56 hexadecimal characters)
- Same structure as SHA-256 but with different initial values
