{
  "summary": "Reviewed the X25519 ASN.1 encode/decode implementation in `p_x25519_asn1.c`, including raw key setters/getters, PKCS#8/SPKI serialization, and the ASN.1 method table. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/ssl/test/runner/hpke/hpke.go`, which is a conventional HPKE implementation for X25519/AES-GCM/ChaCha20-Poly1305 key setup, seal/open, and export operations. I checked for install hooks, hidden subprocess or dynamic code execution, network/exfiltration, credential or environment harvesting, obfuscation, and persistence behavior; none were present in this file.\nReviewed `aws-lc/crypto/ex_data.c`, which implements OpenSSL-style ex_data registration, storage, lookup, and cleanup with callback invocation during object teardown. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/ocsp/ocsp_print.c`, which contains OCSP request/response pretty-printers and string tables for status codes. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
