{
  "summary": "Reviewed `aws-lc/crypto/bytestring/ber.c`, which implements BER-to-DER conversion and implicit string parsing for ASN.1 byte strings. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/modes/gcm_test.cc`, which is a C++ GoogleTest file exercising AES-GCM test vectors plus optional ABI checks for platform-specific GCM/AES routines. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution paths.\nReviewed `aws-lc/crypto/lhash/internal.h`, which is a C header declaring and wrapping AWS-LC lhash APIs and type-safe macros. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none are present in this target file.\nReviewed `aws-lc/ssl/custom_extensions.cc`, which implements TLS custom extension registration, client/server hello serialization, and parse callbacks. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
