      "summary": "Reviewed the MD5 implementation in `aws-lc/crypto/fipsmodule/md5/md5.c`, including initialization, state import/export, block processing, and finalization. I found no concrete indicators of install-time execution, network exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
