{
  "summary": "Reviewed this header-only Wycheproof test utility declaration file, which only exposes parsing and lookup helpers for test vectors (result flags, digest, curve, and BIGNUM helpers). I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior in the target file and found no concrete malicious or supply-chain indicators.\nReviewed this header-only RNG interface in aws-lc's ml-kem code. It only declares a consumer-provided `randombytes` function and a thin inline wrapper around it; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.\nReviewed the Perl code generator in `aws-lc/crypto/fipsmodule/rand/asm/rndr-armv8.pl`, which emits ARMv8 assembly for `CRYPTO_rndr_multiple8` via `arm-xlate.pl`. I checked for install hooks, hidden subprocess chains beyond the expected assembler translation step, network or credential access, obfuscation/packing, dynamic code loading, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/rand_extra/getrandom_fillin.h`, which is a small platform-guard header that defines expected `getrandom` syscall numbers and fallback `GRND_*` constants for Linux builds. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/x509/v3_enum.c`, which is a small X.509 extension helper that maps CRL reason enumerations to human-readable names using static tables and OpenSSL string duplication. 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.",
