Review rev_7ac52594e0f84b66be25e0764055ae10

{
  "summary": "Reviewed `src/aead/aes/ffi.rs`, which is a small Rust FFI wrapper around AES key setup, block encryption, and CTR-mode block processing. I checked for install hooks, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/pkcs8.rs`, which only contains PKCS#8 template, parse, and wrap helpers for key material. I found no concrete indicators of install hooks, network or exfiltration behavior, credential/secret harvesting, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `src/hkdf.rs`, which is a straightforward HKDF implementation over the crate's HMAC primitives. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/ec/curve25519/ops.rs`, which implements Curve25519/Edwards25519 point encoding, scalar multiplication entry points, and FFI bindings to low-level field arithmetic. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `third_party/fiat/asm/fiat_curve25519_adx_mul.S`, an x86_64 assembly implementation of Curve25519 field multiplication using ADX/MULX instructions and stack/register saves/restores. I checked for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
