  "summary": "Reviewed aws-lc/crypto/fipsmodule/digest/digests.c, which is a straightforward set of EVP digest method wrappers for MD4/MD5/RIPEMD160/SHA-1/SHA-2/SHA-3/SHAKE and MD5-SHA1. I checked for install hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/hrss/hrss_test.cc`, a C++ GoogleTest file that exercises HRSS polynomial inversion, key generation, encapsulation/decapsulation, and ABI scratch-space checks using deterministic vectors and `RAND_bytes`. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
