  "summary": "Reviewed aws-lc/crypto/fipsmodule/sha/keccak1600.c, which implements the Keccak/SHA-3 permutation plus absorb/squeeze helpers and an optional asm dispatch wrapper. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, hidden subprocess execution, and other payload-loading indicators, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/crypto/trust_token/internal.h`, which is an internal C header declaring Trust Token / VOPRF data structures, method tables, and serialization helpers. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
