{
  "summary": "Reviewed this header as a numeric helper interface for Montgomery multiplication and limb arithmetic in ring's FIPS big-number code. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in the file.\nReviewed this Rust AES-GCM backend wrapper, which only wires `seal` and `open` into local assembly entry points and handles buffer partitioning and authentication bookkeeping. I found no concrete supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed the generated AArch64 GHASH assembly in `pregenerated/ghashv8-armx-win64.S`. It is a straight cryptographic implementation with no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior present in the file.\nReviewed `src/aead/overlapping/base.rs`, a small Rust helper for managing overlapping mutable slices and range-checked slice access. I found no concrete malicious or supply-chain 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 `src/aead.rs`, which defines the AEAD public API surface, nonce/tag wrappers, and module declarations for AES-GCM and ChaCha20-Poly1305. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, subprocess launches, network or exfiltration calls, credential/secret access, dynamic code loading, obfuscation, or persistence behavior.",
