  "summary": "Reviewed `bignum_tomont_p384_alt.S`, an x86-64 assembly routine that performs Montgomery conversion for the P-384 field element. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, or persistence tampering in this file.\nReviewed `aws-lc/crypto/x509/x_x509.c`, which implements X.509 ASN.1 parsing, serialization, reference counting, and signature accessors. I checked for install hooks, subprocess launches, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators; none were present in this file.\nReviewed `aws-lc/generated-src/mac-x86/crypto/fipsmodule/ghash-x86.S`, a generated x86 assembly implementation of GHASH/GCM with handwritten-style byte opcodes and a constant lookup table. I checked for install hooks, network/exfiltration, credential or environment access, dynamic code loading, obfuscation/packing, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
