I checked it for install-time execution, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, and hidden subprocesses, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `aws-lc/crypto/ec_extra/ec_derive.c`, which derives an EC private/public key pair from caller-supplied secret material using HKDF-SHA256, curve-label key separation, and Montgomery reduction before zeroizing the derived buffer. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malware behavior in this file.",
