{
  "summary": "Reviewed aws-lc/crypto/evp_extra/p_kem_asn1.c, which implements ASN.1 encode/decode and raw accessors for AWS-LC KEM public/private keys. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the generated Windows x86_64 assembly for a P-256 modular inverse routine. It is straight-line cryptographic arithmetic and prologue/epilogue handling; I checked for install hooks, network or exfiltration, credential or environment access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the C implementation of X509 hash-directory lookup and cache population in `aws-lc/crypto/x509/by_dir.c`. It only resolves certificate/CRL files from local directories, caches hashes, and clears expected load errors; I found no concrete indicators of install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution in this file.",
