  "summary": "Reviewed aws-lc/crypto/fipsmodule/ec/simple.c, which contains constant-time elliptic-curve field and point arithmetic plus byte conversion helpers. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/fipsmodule/cmac/cmac.c`, which implements CMAC initialization, update/finalization, subkey derivation, and FIPS service-indicator handling for AES/3DES-backed MAC computation. I checked for install-time hooks, subprocess or network activity, credential or secret access, dynamic code loading, obfuscation, persistence, and other payload-construction behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the target header `aws-lc/crypto/fipsmodule/curve25519/internal.h`, which contains only internal Curve25519/Ed25519 type definitions, feature macros, and function prototypes. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators; none are present in this file.\nReviewed `aws-lc/crypto/x509/t_x509.c`, which implements X.509 certificate and name/signature printing helpers. I found no concrete malicious or supply-chain indicators: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
