🔐 Cryptographic Hash Functions (for Security)

For digital signatures, certificates, password hashing, and security applications

BLAKE3 | 256-bit → Ultimate Security | Ultra Fast | Modern, all-purpose

BLAKE2b | 512-bit → Max Security | Fast | Files, general hashing

SHA3-512 | 512-bit → Very High Security | Moderate | Robust applications

SHA-512 | 512-bit → Higher Security | Moderate | Certificates, high-security

SHA3-256 | 256-bit → High Security | Moderate | Modern apps

SHA-384 | 384-bit → Better Security | Moderate | Certificates, sensitive data

SHA-256 | 256-bit → Standard Security | Moderate | Signatures, integrity checks

⚠️ Legacy Cryptographic Functions

NOT SECURE - Use only for compatibility with old systems

SHA-1 | 160-bit → Broken | Fast | Old signatures only

MD5 | 128-bit → Broken | Fast | Simple checksums only

⚡ Non-Cryptographic Hash Functions (Fast Integrity Checks)

For checksums, data deduplication, and fast file verification

XXH3-128 | 128-bit → Extremely Fast | Modern | Best for large files

XXH3-64 | 64-bit → Ultra Fast | Modern | Quick checksums

CRC32C | 32-bit → Very Fast | Hardware-accelerated | Error detection

CRC64 | 64-bit → Fast | Better collision resistance | Network protocols
