SHA-3 해시 알고리즘 정보

SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family, developed through a public competition by NIST. Based on the Keccak algorithm, it represents a completely different design from SHA-2 and provides enhanced security against potential attacks.

SHA-3 해시 특성

• Based on sponge construction (Keccak algorithm)
• Completely different design from SHA-1 and SHA-2
• 길이 확장 공격에 저항력 있음
• Flexible output sizes: 224, 256, 384, 512 bits
• NIST standard for secure hashing (FIPS 202)

✅ Security Status: SHA-3 is considered cryptographically secure and is recommended for all security-sensitive applications. It provides strong resistance against collision attacks and other cryptographic vulnerabilities.
