{
  "summary": "Reviewed `aws-lc/util/fipstools/acvp/acvptool/subprocess/kdf-components.go`, which parses ACVP KDF test vectors and derives TLS/SSH KDF outputs via a transactable backend. I checked it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this generated Win64 assembly for `beeu_mod_inverse_vartime`, which appears to implement a finite-field modular inverse routine for P-256 using only local arithmetic, stack saves, and normal control flow. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed this header-only Trust Token API declaration file and found no concrete indicators of supply-chain compromise or malicious behavior. It contains exported function prototypes, struct definitions, and error codes only; I checked for install-time hooks, network or exfiltration logic, secret access, dynamic code loading, obfuscation/deobfuscation, and persistence mechanisms, and none are present in this target file.",
