{
  "summary": "Reviewed `aws-lc/crypto/x509/x509_v3.c`, which contains X509 extension helper routines for counting, locating, creating, inserting, and reading certificate extensions. I checked this file for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/include/openssl/mem.h`, which is a public API header declaring memory/allocation helpers, string utilities, and secure-heap compatibility shims for AWS-LC/BoringSSL. I checked it for install-time hooks, hidden subprocess or network activity, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.\nReviewed aws-lc/ssl/test/runner/tls.go, which implements TLS client/server helpers, listener wrapping, dial-with-handshake timeout handling, and PEM certificate/private-key loading and validation. I found no concrete malicious or supply-chain indicators in this file: no install hooks, no credential harvesting, no hidden downloads or dynamic code loading, no obfuscation, and no persistence or environment tampering.\nReviewed the x86-64 assembly implementation of `bignum_tomont_p384`, which performs Montgomery conversion for P-384 using fixed constants and register-only arithmetic. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present in this file.",
