      "summary": "This file is a self-contained SHA-3/Keccak implementation for jitterentropy, including absorb/squeeze logic, a built-in self-test, and allocation helpers. I reviewed it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious indicators.",

      "summary": "Reviewed the target header `aws-lc/third_party/jitterentropy/jitterentropy-sha3.h`, which only declares SHA3 context macros, a `sha_ctx` struct, and function prototypes for the jitterentropy SHA3 implementation. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed the internal jitterentropy timer implementation in `aws-lc/third_party/jitterentropy/jitterentropy-timer.c`. It only allocates a small context, spawns and joins a local worker thread for timer emulation, and gates that behavior behind compile-time/runtime flags; I found no concrete indicators of install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence.",
