      "summary": "Reviewed `aws-lc/crypto/siphash/siphash.c`, which is a straightforward SipHash-2-4 implementation over an input buffer and 128-bit key. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
