{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/evp/p_kem.c`, which implements EVP_PKEY KEM setup, key generation, encapsulation/decapsulation, and raw key helpers for AWS-LC. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential or secret harvesting, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nThis target file is a platform-specific x86_64 BIGNUM accelerator that implements multiprecision add, subtract, multiply, and square routines with inline assembly for AWS-LC/OpenSSL-style arithmetic. I checked it for install hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
