SHA3-224 Hash Generator
About SHA3-224
SHA3-224 is part of the SHA-3 (Secure Hash Algorithm 3) family, which was selected as the winner of the NIST hash function competition in 2012. It's a modern cryptographic hash function that provides enhanced security compared to older algorithms like MD5 and SHA-1.

Comparison with Other Hash Functions
SHA3-224:
- Based on Keccak sponge construction
- Resistant to length extension attacks
- Can be more efficient in hardware
- Different internal structure
Traditional Hash Functions:
- Based on Merkle–Damgård construction
- Vulnerable to length extension attacks
- Often faster in software on CPUs
- More widely adopted currently
SHA3-224 offers enhanced security features and a different design approach compared to traditional hash functions.
Best Practices
- Always use a salt when hashing passwords
- Store hashes securely
