      "summary": "Reviewed `aws-lc/crypto/rand_extra/getentropy.c`, which provides a small `CRYPTO_sysrand` implementation that repeatedly calls local `getentropy()` in bounded chunks and aborts on failure. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed `aws-lc/crypto/rand_extra/getentropy_test.cc`, which is a small gtest that exercises `getentropy()` by checking nonzero/unique output and oversized-request error handling. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.",
