{
  "summary": "Reviewed this ARM64 AES-XTS encryption routine and found it to be a straight cryptographic implementation: it loads AES round keys, applies AES rounds, handles tweak/cipher-stealing logic, and returns without any install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior. No concrete malicious or supply-chain indicators were present in the target file.",
