{
  "summary": "Reviewed `aws-lc/crypto/x509/x509_req.c`, which implements X.509 certificate request accessors and attribute/extension helpers. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the ARM assembly implementation of GHASH (`gcm_init_v8`, `gcm_gmult_v8`, `gcm_ghash_v8`) in `aws-lc/generated-src/linux-arm/crypto/fipsmodule/ghashv8-armx.S`. It is a generated crypto routine that performs local vectorized math and data movement only; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior.\nReviewed the generated AArch64 Windows assembly for the Keccak-1600 permutation. It is a straight-line cryptographic state transform with a fixed round-constant table and stack/register save-restore logic; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain payload behavior.\nReviewed this target x86-64 assembly implementation of `bignum_madd_n25519_alt`, which performs a Curve25519/Ed25519 scalar multiply-add and modular reduction. I checked for install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in the file.",
