  "summary": "Reviewed this header-only RSAZ exponentiation interface and found no concrete malicious or supply-chain indicators. The file contains compile-time feature guards and function declarations for AVX/AVX512 modular arithmetic, with no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/x509/t_x509.c`, which implements X.509 certificate and signature printing helpers using OpenSSL BIO/ASN1 APIs. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration calls, credential/secret access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/bn/gcd_extra.c`, which implements constant-time big-number GCD, relative-prime checks, LCM, and modular inverse routines for AWS-LC/FIPS. I checked for install-time hooks, hidden subprocesses, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence behavior; none were present in this file.",
