  "summary": "Reviewed aws-lc/util/fipstools/acvp/acvptool/subprocess/subprocess.go, a Go wrapper that launches a child process and exchanges ACVP test-vector messages over stdin/stdout with JSON/hex encoding helpers. I checked for install-time hooks, hidden subprocesses beyond the explicit exec.Command path, network or exfiltration behavior, credential or environment harvesting, dynamic code loading, obfuscation, and persistence; no concrete malicious or supply-chain indicators were found in this file.\nReviewed `aws-lc/crypto/fipsmodule/sha/sha1.c`, which is a straightforward SHA-1 implementation with initialization, update/finalization, state import/export, and CPU-dispatching compression code. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.",
