      "summary": "Reviewed the ChaCha20-Poly1305/XChaCha20-Poly1305 implementation in `aws-lc/crypto/cipher_extra/e_chacha20poly1305.c`. It contains direct AEAD encryption/decryption, tag generation, and EVP cipher plumbing, and I found no concrete indicators of install-time execution, network exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "Reviewed aws-lc/crypto/cipher_extra/e_des.c, which only defines DES and 3DES EVP cipher wrappers and key setup/cipher dispatch for CBC and ECB modes. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in this target file.",

      "summary": "Reviewed `aws-lc/crypto/cipher_extra/e_null.c`, which implements the EVP null cipher by initializing no key material and copying input bytes to output unchanged. I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
