  "summary": "Reviewed `aws-lc/crypto/fipsmodule/rsa/padding.c`, which implements RSA PKCS#1/PSS padding and verification helpers. I checked for install-time hooks, network or exfiltration paths, credential or secret access, dynamic code loading, obfuscation/packing, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/sha/sha256.c`, which is a conventional SHA-224/SHA-256 implementation with FIPS service-indicator handling and CPU-capability dispatch. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.",
