{
  "summary": "Reviewed `aws-lc/crypto/rand_extra/trusty.c`, which is a small Trusty-specific RNG shim that forwards `CRYPTO_sysrand` to `trusty_rng_hw_rand` and aborts on error. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, or other supply-chain compromise in this target file.\nReviewed the `aws-lc/include/openssl/siphash.h` header, which only declares the `SIPHASH_24` C API for SipHash-2-4 and contains no executable logic. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this header-only Dilithium signing interface, which only declares namespaced crypto_sign/challenge APIs and includes local parameter/poly headers. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed `aws-lc/crypto/dilithium/sig_dilithium3.c`, which is a thin wrapper layer that forwards Dilithium3 keypair/sign/verify calls to the reference PQClean-style implementations. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this header-only file, which just declares ML-KEM polyvec helper APIs and a struct definition. I found no concrete malicious or supply-chain indicators in the file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.",
