{
  "summary": "Reviewed `aws-lc/crypto/cipher_extra/e_aesctrhmac.c`, which implements AES-CTR plus HMAC-SHA256 AEAD seal/open routines and key initialization. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/crypto/fipsmodule/rsa/internal.h`, which only declares RSA method/state structures and helper prototypes for padding, blinding, and private-key transforms. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.\nReviewed `aws-lc/util/fipstools/acvp/acvptool/subprocess/rsa.go`, which only parses RSA ACVP test vectors and dispatches them to an existing `Transactable` for key generation, signature generation, and verification. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this target x86-64 assembly implementation of P-384 Montgomery multiplication and found no concrete supply-chain indicators: it is a self-contained arithmetic routine that only uses register/memory operations, with no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior. The control flow is limited to the expected multiply/reduce/conditional-subtract sequence and a normal function return.",
