Review rev_193a41e64d1a4d56b0448fafc2aceeca

{
  "summary": "Reviewed this Kyber `polyvec` header, which only declares the `polyvec` struct and namespace-wrapped prototypes/macros for compression, serialization, NTT, reduction, and addition. I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in the target file.\nReviewed `aws-lc/crypto/rsa_extra/rsa_print.c`, which is a small OpenSSL-compatible RSA formatting wrapper that converts an `RSA` into an `EVP_PKEY` and prints it to a `BIO` or `FILE *`. I found no concrete supply-chain indicators in this target file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the Kyber KEM header at `aws-lc/crypto/kyber/kem_kyber.h`; it only declares constants and legacy KEM accessor prototypes and does not contain install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior. No concrete malicious or supply-chain indicators were found in this target file.\nReviewed `aws-lc/crypto/spake25519/internal.h`, which only defines the SPAKE2 internal state enum and `spake2_ctx_st` layout with key, name, and password buffer fields plus a test-oriented `disable_password_scalar_hack` flag. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the generated x86_64 Windows assembly stub for AVX-512 AES-GCM symbols. It only defines exported labels and immediately traps/returns (`ud2`/`ret`) with no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators.",
