{
  "summary": "Reviewed `aws-lc/crypto/obj/obj_test.cc`, which is a unit test for OID/object identifier parsing and formatting in AWS-LC. I found no concrete supply-chain or malicious indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/constant_time_test.cc`, which is a GoogleTest unit test for constant-time comparison, selection, memory-compare, and value-barrier helpers using locally generated random buffers. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.\nI reviewed `aws-lc/crypto/ecdsa_extra/ecdsa_asn1.c`, which implements ECDSA signature size calculation plus ASN.1/DER parse and marshal helpers. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, or hidden subprocess execution.\nReviewed `aws-lc/crypto/fipsmodule/bn/cmp.c`, which implements BIGNUM comparison and predicate helpers such as constant-time unsigned compare, signed compare, word/zero/one checks, power-of-two detection, and equality testing. 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, persistence, or hidden subprocess execution.\nReviewed `aws-lc/ssl/dtls_method.cc`, which only defines DTLS method vtables and small state-transition helpers for handshake read/write epochs. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.",
