{
  "summary": "Reviewed the generated AArch64 Keccak-1600 assembly implementation and found it to be a straight cryptographic permutation routine with fixed constants, state mixing, and normal function entry/exit handling. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the AArch64 KeccakF1600 implementation in `aws-lc/generated-src/linux-aarch64/crypto/fipsmodule/keccak1600-armv8.S`. It contains only local crypto state manipulation, round constants, and function prolog/epilog code; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/include/openssl/sha.h`, a pure C header that only declares SHA-1/SHA-2 types, constants, and exported function prototypes. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/ssl/dtls_record.cc`, which implements DTLS record parsing, replay-window tracking, and record sealing for encrypted traffic. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.",
