{
  "summary": "Reviewed the generated ARM assembly in `aws-lc/generated-src/ios-arm/crypto/fipsmodule/ghashv8-armx.S`, which implements GHASH/GCM primitives for iOS ARM and contains only fixed vector arithmetic, loads/stores, and control flow for the crypto routine. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\n`aws-lc/crypto/perlasm/arm-xlate.pl` is a Perl translation script that rewrites ARM/ARM64 assembly into target-specific output with symbol/section handling and minor syntax normalization. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/ec/util.c`, which contains a single constant-time scalar recoding helper for elliptic-curve point multiplication and extensive explanatory comments. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators; none were present.\nReviewed `aws-lc/crypto/fipsmodule/aes/key_wrap.c`, which implements RFC 3394/RFC 5649 AES key wrapping and unwrapping with FIPS service-indicator bookkeeping. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, subprocesses, network/exfiltration, credential or secret harvesting, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering behaviors.",
