What is SHA-3?
SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family, designed by the NIST as a successor to SHA-2. It is based on the Keccak cryptographic function and provides enhanced securityfeatures.
How SHA-3 Works
SHA-3 uses a sponge construction, which absorbs the input data and then squeezes out the final hash value. Unlike SHA-2, it is not based on the Merkle-Damgård construction, making it more resistant to certain cryptographic attacks.
Why Use SHA-3?
SHA-3 is widely used for:
- Increased resistance to collision and pre-image attacks.
- Blockchain and secure communication applications.
- Providing an alternative to SHA-2 for future-proof security.
Security of SHA-3
SHA-3 offers robust security and is designed to withstand emerging cryptographic threats. While SHA-2 remains widely used, SHA-3 provides an additional layer of security for applications requiring stronger cryptographic guarantees.
