{
  "summary": "Reviewed `aws-lc/ssl/test/handshaker.cc`, a local test harness that parses control messages, drives `SSL_do_handshake`, and serializes handback/handshake-hint state over file descriptors. I found no concrete signs of install-time execution, network exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/ssl/test/mock_quic_transport.cc`, a QUIC test transport helper that reads and writes framed handshake, application, and alert records through a BIO and forwards them into SSL/QUIC test APIs. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration logic, credential or secret harvesting, dynamic code loading, obfuscation, persistence tampering, or hidden subprocess execution.\nReviewed the x86-64 assembly routine `bignum_montredc`, which implements Montgomery reduction with ABI setup, register saving/restoring, and arithmetic-only loops. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/evp_extra/p_x25519_asn1.c`, which implements X25519 ASN.1 public/private key encode, decode, compare, and size helpers for EVP_PKEY. I found no concrete supply-chain or malicious indicators: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution in this file.",
