{
  "summary": "Reviewed aws-lc/crypto/ocsp/ocsp_client.c, which implements OCSP request/response helper routines and validity checks for certificate status handling. I checked for install-time hooks, network/exfiltration, credential or secret access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution; none were present in this file.\nReviewed `aws-lc/ssl/tls_method.cc`, which defines TLS method selection and handshake state transitions plus no-op X509 method shims for the SSL library. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence; the file is conventional protocol plumbing only.\nReviewed `bignum_tomont_p384_alt.S`, a hand-written x86-64 assembly routine that performs constant-time Montgomery reduction/conversion for P-384 using register arithmetic and stack save/restore only. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution paths, and found no concrete malicious or supply-chain indicators.",
