Review rev_01bdc1dc81b74204acd2938105665dba

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/jacobi.c`, which implements the Jacobi symbol for BIGNUMs using local arithmetic and OpenSSL error handling. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/ml_kem/ml_kem_ref/ntt.c`, which is a static Kyber/AWS-LC number-theoretic transform implementation: precomputed `zetas` constants plus `ntt`, `invntt`, and `basemul` arithmetic helpers. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this target file.\nReviewed the Kyber NTT implementation in `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/ntt.c`, including the hard-coded `zetas` table, `fqmul`, `ntt`, `invntt`, and `basemul` routines. No concrete malicious or supply-chain indicators were found: there are no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/evp_extra/p_hmac_asn1.c`, which defines the HMAC `EVP_PKEY_ASN1_METHOD` plus key set/get/free helpers for OpenSSL-compatible key handling. I found no concrete malicious or supply-chain indicators: there are no install hooks, network/exfiltration paths, credential harvesting, dynamic code loading, obfuscation, persistence, or hidden subprocess execution in this file.\nReviewed this header-only P-256 crypto interface and found only type declarations, constants, and function prototypes plus one small inline Montgomery-conversion helper. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.",
