      "summary": "Reviewed the PBKDF2-HMAC implementation and the SHA1 convenience wrapper in `aws-lc/crypto/fipsmodule/pbkdf/pbkdf.c`. It performs deterministic key derivation with HMAC, and I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",

      "summary": "The target file is a PBKDF2 unit test suite covering empty password/salt cases, RFC 6070 vectors, SHA-2 vectors, and zero-iteration behavior. I checked for install-time hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior.",
