{
  "summary": "Reviewed `aws-lc/crypto/x509/v3_info.c`, which implements ASN.1/X.509 Authority Info Access encoding and decoding helpers. I found no concrete supply-chain or malicious indicators: there are no install hooks, network or exfiltration logic, credential or environment harvesting, dynamic code loading, obfuscation/deobfuscation, or persistence behavior in this file.\nReviewed `aws-lc/include/openssl/thread.h`, a public C header that only declares thread/mutex types and AWS-LC/OpenSSL compatibility APIs, plus deprecated no-op locking callbacks. I checked for install-time hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the ASN.1/X.509 public-key helper in `aws-lc/crypto/x509/x_pubkey.c`, including its DER re-encode/parse callback path and public-key getters/setters. I found no concrete malicious or supply-chain indicators: there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behaviors in this file.\nReviewed the ARM assembly implementation of `bignum_madd_n25519_alt`, which performs a constant-size curve25519/edwards25519 modular multiply-add and writes the result back to the caller-provided buffer. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/util/fipstools/acvp/acvptool/test/check_expected.go`, a Go test harness that parses test definitions, optionally decompresses `.bz2` inputs/expected outputs, and runs a caller-supplied tool binary with `os/exec` to compare results. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic remote code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
