  "summary": "Reviewed `aws-lc/crypto/fipsmodule/modes/internal.h`, which is a C header of AES/CTR/GCM/XTS type definitions, constants, and function declarations for AWS-LC's FIPS modes code. I found no concrete malicious or supply-chain indicators in the file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering behavior.\nReviewed `aws-lc/crypto/fipsmodule/rand/urandom.c`, which is a platform-specific entropy acquisition module using `getrandom`, `/dev/urandom`, OpenBSD `arc4random_buf`, and Apple `CCRandomGenerateBytes`. I checked for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
