Xxhash Vs Md5 -

While MD5 is still ubiquitous, it is considered cryptographically dead. You cannot rely on it to verify that a file hasn't been maliciously altered by an attacker. However, it is still safe to use for accidental corruption detection (e.g., a bit flip during a hard drive transfer).

| Feature | MD5 | xxHash (XXH3) | | :--- | :--- | :--- | | Output Size | 128 bits (16 bytes) | 32, 64, or 128 bits | | Speed | Slow (300 MB/s) | Extremely Fast (30+ GB/s) | | Cryptographic Security | Broken (Not secure) | None (Zero security) | | Collision Resistance | Moderate (Adversarial possible) | Low (Trivial if targeted) | | Avalanche Effect | Good | Excellent (Better than MD5) | | Use Case | Legacy checksums, non-adversarial dedup | Databases, Hash Tables, Networking, Compression | | Standardization | RFC 1321 | None (Community standard) | xxhash vs md5

You have a stream of sensor data coming in, and you want to tag unique entries. While MD5 is still ubiquitous, it is considered
